HEAL

Windows of the Soul and Door to a Bright Future

by Elena & Karin Semler

It is often said that “eyes are the windows of the soul.” Not only that; they are also a gateway for education and deeper understanding. 

During late November and December 2021, to serve students at Heshangzhuang and Zengyi Primary Schools in Yunnan province, CWEF partnered with staff from the local nonprofits Education in Sight and the Zhengxin Social Work Service Center in Wuding county to provide vision screening and to teach children about the importance of eye care.

The eye care activities for 134 students at these two primary schools in Wuding County are just one small piece of a broader, comprehensive program the schools have partnered with CWEF to facilitate, which is called HEAL (“Health Education, Advocacy & Literacy”).

HEAL addresses the need for proper health-related equipment and resources, along with the deeper knowledge and behavior change needed for students to lead a full, healthy life.

Eye health is a key – and sometimes missing – piece, as one student noted:

“It was the first time we tested our eyesight, and we realized that eyes are so important. The world is blurry if you don’t see well. If you are nearsighted, you should wear glasses with the correct prescription. We should develop good habits and do eye exercises carefully.”

Eye screening with Mr. Yin of Education in Sight

Mr. Yin, the trainer from Education in Sight, reflected:

“The students were very curious to learn that the proportion of myopia among rural children is much lower than their peers in the cities.”

The recent global increase in myopia (or nearsightedness)is attributed to the increased use of electronics and screen time in young children. In addition to the training, books about proper eye care were given to the students, and all the students were screened for myopia.

Myopia can be most easily corrected by eyeglasses. Of the students tested, around 7% were found to have myopia. Most of these students were given free glasses available directly from Education in Sight, and the others were advised to go to the hospital for further screening.

Understanding proper eye care methods and providing glasses is important because without this intervention, more children are vulnerable to developing myopia or other eye issues. Working to prevent and treat eye issues like myopia can help the students in their general health and school education. The teachers at the Heshangzhuang and Zengyi schools reported that the screenings and health education activities were very meaningful, and will further give them the opportunity to follow up with ongoing health education related to eye care and their students’ overall health.

CWEF, together with our local partners, would not be able to facilitate the HEAL program or provide this free eye health education, eye tests, or glasses for these students from underserved communities without generous supporters like you.

Thank you for your generous donations. You are making a clear difference in these children’s lives and giving them the chance to see a bright future.

No Longer “Underwater” (Thanks to Clean Water)

Maiy was stressed and worried. His family was “underwater.”

As a new husband to his wife Chantou and adoptive father to her two sons, Maiy was feeling the weight of the family’s debt. They had taken out a microfinance loan to buy equipment for their family’s small farming operation, but now Maiy couldn’t even stay healthy enough to keep working every day in the fields in order to pay down the debt.

He and the rest of the family would frequently fall ill with diarrhea and painful stomach aches. At the time, they didn’t know the cause of their sickness: their daily habit of drinking the rainwater that they collected at their home in rural Tboung Khmum province, Cambodia.

With their frequent waterborne illness, the family’s medical expenses piled on top of their other daily expenses, which piled on top of their debt. Maiy couldn’t see a way out.

Then, through a connection with their local Christan church, Maiy and Chantou learned about a BioSand Water Filter project in their community, made possible by your generous gifts to CWEF.

They learned more about the water filters from their pastor, and they attended a training session where they learned about the dangers of drinking unsafe water, as well as different ways they could protect themselves and their kids.

Maiy and Chantou participate in HEAL training

Finally, they received the gift of a BioSand Water Filter in 2021. Since then, they have had the great blessing of drinking clean and safe water every day.

Maiy recently shared:

“Now, I feel relaxed and happy after getting our Biosand Water Filter from CWEF. We can filter either rainwater or well water for our family’s daily drinking needs. I also regularly bottle the water from the filter and take it with me to the fields when I go out to work.”

Maiy, Chantou, and their boys don’t get sick as often as they did before, and now Maiy has plenty of time and energy to do his farming work each day. He estimates that they will have the microfinance loan debt paid off in just 7 more months.

As a committed Christian and a member of their local church, Maiy and Chantou have also been led to participate as trained local advocates in the broader community health and development program called HEAL (“Health Education, Advocacy & Literacy”), which is sponsored by CWEF and facilitated in partnership with the local pastor, Sareun, and his wife, Ly. The team of HEAL advocates in their community have participated in a series of in-depth training sessions, and are committed to being agents of positive change in their area.  

Maiy and his family now want to do what they can to bless and serve others in their community, as they themselves have been blessed through the local church, in partnership with CWEF.

Maiy closed our conversation with this simple and selfless note of gratitude and hope:

“My family members all got healthier now, and I hope to see that God will use my family in the future to share the Gospel with others.”

HEALTHY BODIES, HEALTHY MINDS, HEALTHY PLANET

Students at Anla and Heshangzhuang Primary School in rural Yunnan province ended the previous school year and started the new school year strong and healthy. Students at both schools participated in TOT (“Training of Trainers”) activities as part of the ongoing HEAL (“Health Education, Advocacy & Literacy”) program facilitated by the CWEF team and our local partners. These student health advocates will go on to serve others in their families and school communities by sharing the knowledge and healthy habits they have learned through this series of HEAL training activities over the span of 1-2 years.    

Before their schools broke for the holiday, in June 2021 students at Anla and Heshangzhuang learned knowledge and practiced healthy behaviors related to personal hygiene, COVID-19 prevention, healthy diet, eye care, disaster preparedness, and basic first aid training.

These HEAL Training of Trainer sessions were delivered as a collaborative effort — trainers from CWEF along with several partner organizations, including eye care and vision-focused non-profit Education in Sight, Zhengxin Social Work Service Center of Wuding county, and the Yunnan Mountain Eagle Rescue Service Center. Working in concert, our organizations can achieve more, and the training we provide to the students is more effective and has a stronger impact. 

Of equal importance is the varied mode of training that is used during these sessions. Our trainers use games, songs, videos, demonstrations, simulations, and other practical exercises to engage different parts of the students’ bodies, brains, and emotions, so that the knowledge and habits learned will have a better chance of sticking with them, and later, spreading to others in their community.

Jenny Chu of CWEF shares: 

“This way of combining theory with practice makes students learn more intuitively. We are helping them to enhance their awareness first, and then to support their knowledge with action.”

Most recently, in September 2021, students at Heshangzhuang Primary School participated in the third session of their HEAL student health advocate training. After learning to take care of their own health and that of their family and friends, they were introduced to the concept of caring for the health of the planet. The training facilitators framed this sometimes complex topic in more simple terms that connected students back to health concerns they are familiar with:

“The Earth has a fever. How can we help the Earth to be healthy?”

Planting The Seeds of a Dream

CWEF’s vision is a world of “thriving communities, serving and inspiring hope in others.”

This is not a “one and done” type of goal—change takes time and real sustainable change happens in the lives of individuals and the communities they serve and inspire. Sixteen-year-old Jianfang is a living example of the impact of becoming a student Health Advocate through the HEAL program.

In 2016, CWEF facilitated a holistic health project in Xishipo, Jianfang’s home village in Lufeng county, Yunnan province. CWEF partners helped to support the construction of various clean water and health-related infrastructure in the village, including a 30 cubic meter water cistern, pumping stations, solar-heated shower rooms, hand-washing stations, garbage repositories, and drinking water pipelines to each household. A hallmark of the HEAL (Health Education, Advocacy & Literacy) project is providing health education and hygiene training (the “software”) for adults and youth, alongside the new infrastructure (the “hardware”).

Jianfang, who is from the Miao minority group, was then 11 years old when the HEAL project was initiated. Jenny Chu, CWEF’s Senior Programs Director in Yunnan, shares about the 2016 training:

“This was the first time for CWEF to use the local language, instead of Mandarin, for the health training. Using the Miao language not only solved the difficulty of knowledge transfer due to language barriers but it also helped to better encourage feelings of solidarity among the participating villagers.”

The health training took place in two phases. The first focused on personal hygiene, environmental hygiene, and nutrition. The second phase of training included information to prevent common diseases, use of medicines, training for safe pesticide use, women’s health care, accident prevention, and substance abuse awareness. Jianfang was in the third year of middle school when she first learned the new information and became a Health Advocate committed to share her new learning with her peers.

Today, Jianfang is in high school and is learning English (by way of an app), together with her intense schedule of daily school work and regular preparation for the looming university entrance exam. The training she received as a HEAL health advocate five years earlier has played a significant role in her life. She shared that the HEAL training planted the seed of a dream. “When I was in primary school, I didn’t know what kind of person I would become in the future. I didn’t have ideas about a future career.”

During the training Jianfang participated in role play presentations for different health promotion activities. “I chose the theme of ‘prevention and treatment of a cold’ and played the role of a doctor. Through this role play I understood the significance of relieving the pain of others.”

Soon after, Jianfang experienced real-life struggles in her family when her sister needed the care of a doctor.

“It takes a lot of time to wait in line to see a doctor, and the result is not always satisfactory,” Jianfang recalls. “At that time, I deeply felt that if I were a doctor, this kind of trouble could be reduced and my family could possibly avoid going to the hospital when they were sick, saving a lot of trouble.”

She also noted the impact of COVID-19: “The whole world is in panic and isolation. When we see the medical staff who stay on the front lines fighting against the virus without sleep or lunch breaks, we are moved.” Now, Jianfang is all the more determined to become a doctor.

Jianfang is inspired to become an “international rescue doctor,” so that she can go to “more difficult places to help those who are really in need.”

Because of your generous giving, young Health Advocates like Jianfang learn life-changing health practices and mindsets. In her case, health education planted a seed and opened her eyes to see how she could make a difference both as a youth Health Advocate but also one day as a doctor.

The vision of “thriving communities, serving and inspiring hope in others” has a name and face: Jianfang from Xishipo village.

Cultivating a Healthier Future for Mrs. Hun’s Family

by Karin Semler, CWEF Board Member

In fall 2020, CWEF staff and local partners surveyed 50 families in several villages in Tboung Khmum province to assess their health needs. A request for water wells had been received, and research was done to assess the overall health situation, as well as other needs and opportunities in the area.

Mrs. Hun, her husband and 16-year-old son are one of the families being served by CWEF’s HEAL (Health Education, Advocacy & Literacy) project, which is providing Water Wells and BioSand Water Filters in addition to HEAL community health education training, in which local health advocates are identified and trained through a series of in-depth Training of Trainers (TOT) sessions.

Mrs. Hun’s family

Many families, like that of Mrs. Hun, face a myriad of challenges. Her husband of 28 years is disabled, adding difficulty for eking out a living in the countryside. Sadly, their son has also suffered from the after-effects of meningitis, which he contracted at the age of nine. Lack of clean water compounded the health problems for Mrs. Hun and her family.

The HEAL community health training seeks to provide both a growth mindset around community needs and opportunities, and specifically a deeper awareness of healthy habits related to basic health, sanitation, and hygiene. CWEF staff must find creative ways to provide the training to ensure understanding and encourage a change in behavior. In the case of this HEAL health education training, roughly a third of the participants are illiterate. The effectiveness of BioSand Water Filters and new water wells can only be sustained through health education and the integration of new healthy habits.

HEAL TOT (Training of Trainers) at Tboung Khmum

For this work, CWEF’s Cambodia team uses the mindsets and resources from the Global CHE (Community Health Evangelism) Network. In Tboung Khmum, we are partnering with Pastor Chea Sareun, Deaconess Kim Ly, members of the local church, and others from the surrounding villages who want to work toward positive change in their own communities.

CWEF projects provide a platform for encouraging sustainable change, aiming for long-term improvements in people’s lives. Project recipients are treated as partners as they receive awareness and training to enhance their livelihoods. Projects like HEAL provide both needed infrastructure, such as water filters and/or water wells, and deeper health and hygiene education for the whole community.

CWEF’S Kanhchana Thoy, with local church partners

Gifts like yours provide life-changing BioSand Water Filters to families like that of Mrs. Hun. Her husband and son will have an improved quality of life as they are spared from additional water-related illnesses. Daily life for Mrs. Hun is positively changed as her access to clean, reliable water is given through your generous support.

Meili’s Meaningful Service and Promising Future

“I hear and I forget; I see and I remember; I do and I understand,” is a well-known Chinese proverb attributed to Confucius. Active involvement in community health education is a hallmark of the HEAL program, through the training of adult and children health advocates.  

CWEF’s Senior Programs Director, Jenny Chu, shares:

“There is a great advantage to training young health advocates since they easily learn and can change their behavior. Once they have new health knowledge—like the importance of hand washing or brushing their teeth—kids can develop good habits and improve their wellness.”

Nineteen-year-old Meili is a high school senior in Lufeng County, Yunnan Province. She is from the Miao people group, which has its own unique language and culture. Meili was trained as a local health advocate and played a key role in the HEAL training activity in her home village of Beiyinqing during December 2020.

“Most older adults and younger children [in Beiyinqing] do not understand Mandarin Chinese. Meili, who is bi-lingual, explained the health lessons in the Miao language and combined the information with her own personal experience.”

Jenny Chu

Made possible by your generosity, a total of 18 children and 20 adults participated in the December training session, which covered personal hygiene, coronavirus prevention, and safe use of pesticides for the adults. Proper handwashing has always been a cornerstone of the HEAL curriculum, but “now school teachers value this part of the project even more. What happened in 2020 has drawn more attention to the importance of health education and good hygiene habits.”

Because of your generous gifts to the HEAL project, Beiyinqing village will complete construction of four new water cisterns in time for the Spring Festival (Chinese New Year) holiday. The new facilities will improve access to drinking water for the villagers, increase water access for domestic and livestock use, and increase irrigation reservoirs, improving farming and animal husbandry for the farmers in Beiyinqing. All of these improvements will improve the personal health and environmental sanitation for the whole community.

Parents in the village value their children’s education and support the training of youth health advocates and the subsequent education of their peers. The water and hygiene projects for the community can help to raise the quality of life and income for the families in the village.

A common path for those who are educated is to later leave Beiyinqing in search of better paying work, to help support their family members back in the village. The adults hope to raise the standard of living at home, so that their talented youth don’t need to leave for work, but can remain an integral part of community life. 

Meili shares this outlook of internal motivation to solve problems and find solutions without waiting for outside help. Her mother has admired Meili’s persistence and enthusiasm for learning. She hopes Meili will be able to go to a good school and have a bright future.

Meili is an exemplar of a peer leader, having already volunteered in other public welfare activities in the summer of 2020. She brought valuable skills, ideas, and language ability to the CWEF health education training for younger students in her village. Students who participated in the health education training will serve as health advocates for their fellow students—teaching them important health knowledge and modeling good habits.

As she looks to her own future, Meili hopes to study theology at a university in Yunnan, so that she can continue to teach and serve her Miao people in their own language and culture.

Thank you for your partnership in making our shared vision become a reality—where villages like Beiyinqing filled with people like Meili can grow into thriving communities, serving and inspiring hope in others.

BUILDING HEALTHY LIVES IN RURAL YUNNAN

The children were amazed to see the purple glow that emerged from on their classmate’s hands under the black-light. The idea of invisible bacteria and contaminants is difficult for anyone to understand. As part of CWEF’s health education curriculum, students participate in a simulation activity in which they see the transfer of ‘bacteria’ from hand to hand contact. The ‘bacteria’ is a transparent powder that is easily spread through contact. The transmission path can be seen when a black-light exposes the invisible fluorescent powder.

In December 2019, CWEF Health Director Jenny Chu led 30 children from two primary schools in Wuding county in rural Yunnan province through a two-day health education “Training of Trainers” session as a part of the HEAL (Health Education Advocacy & Literacy) program. These students will serve as health advocates—providing instruction and modeling to their peers in the areas of good hygiene and health promotion. 

The World Health Organization promotes proper handwashing to prevent illness and reduce the spread of disease. Once rural areas have access to reliable and safe drinking water, additional health and hygiene practices need to be introduced. Through HEAL training, children learn how to thoroughly wash their hands and gain knowledge about bacteria and contaminant transmission. Through reference books, hands-on training, the germ-glow black-light simulation, and a handwashing song, student health advocates learn knowledge and practice good habits. They are also equipped to teach their peers about the importance of handwashing and serve as models for this healthy habit.

In addition to handwashing, the program addresses oral hygiene and proper teeth brushing techniques, healthy diet and nutrition, and importance of keeping a sanitary environment. The training provides children with critical information for healthy living and opportunities for the health advocates to engage with their peers by sharing the information and leading activities. CWEF gathers baseline information regarding the knowledge and personal hygiene practices of the students in order to provide supplemental training and information.

Protection for Today, Health for Tomorrow

In May 2020, student health advocates at Zengyi primary school in Yunnan province received training in specific health knowledge and behaviors, which they have committed to pass on to their peers and to model in their daily life.


Guimei, a 10-year-old student at Zengyi, was selected to be a student health advocate because of her personal discipline, confidence, and natural leadership qualities. She and her family are from the Miao ethnic minority group, and because her home is far away Guimei lives at the school during the week. At home, her family does not have access to sanitary toilets or bathing facilities, so Guimei bathes during the week when she boards at school. It was also at school that Guimei learned crucial health and hygiene lessons through CWEF’s HEAL program.



“I learned to wash my hands frequently, wear masks, have good hygiene, and not eat junk food,” shares Guimei. “If you don’t wash your hands, you will get sick easily. If you don’t brush your teeth, you will get cavities, which will affect your appearance.”

When Guimei returned home on the weekends, she advocated for healthy habits with her parents and grandparents.

“I shared my knowledge of handwashing with my mom and dad, and grandparents. Apart from Grandma, they all think it’s very good. Grandma thinks it’s troublesome and doesn’t like this way of washing hands.”  

In addition to these topics, Guimei and other student health advocates learned how viruses are transmitted, how to avoid and treat diarrhea, and how to avoid accidental injuries such as scalding. Health advocate and trainer Ms. Cao shares, “The HEAL project is designed for the basic needs of the rural population. The personal hygiene habits of rural community and primary school students, as well as the basic conditions for maintaining these habits, are still lacking. The project starts from improving people’s awareness and solving the problems of water, hand washing, bathing, and other essential facilities, which complement each other.” 

These teachings have been foundational to additional education in the current season about the novel coronavirus, COVID-19. The HEAL training included instructions for proper mask wearing and prevention of this new infectious disease. Guimei shares,  

“I hope the coronavirus will end soon, so everyone can return to school. Studying at home is lonely. I feel sad when I cannot learn more knowledge.” 

Guimei’s principal, Mr. Hua, reflected, “The health project is very good, especially for improving the students’ basic health habits. There are more and more students who wash their hands with soap and hand sanitizer. During the dry season, there is a shortage of water in the reservoir. I hope that we can also solve the problem of water shortage.”  



Beyond the current health crisis, Ms. Cao affirms the HEAL program’s value over the long-term for people in rural China: “Good personal hygiene habits and behaviors are the basis for maintaining health, and should continue to be the focus. Chronic disease has been a major health problem in China, and the root of chronic disease can be traced back to childhood.”  

With their new knowledge and the formation of healthy habits, students like Guimei have a better chance for a healthy future in which they can thrive. About her own future, Guimei shared:              

“I want to be a model when I grow up. I like singing and dancing very much!”

Project Success Leads to New Work in Tboung Khmum

Since 2011, CWEF has collaborated with local churches and government partners in Cambodia’s Kampong Thom province to improve health through holistic development projects. A pillar of CWEF’s work in Kampong Thom has been the Biosand Water Filter project supported by your generous gifts, which have provided local families with convenient access to clean and safe water in their homes, reducing the impact of water-borne illnesses. Additional work in this area over the past decade has included an Animal Gift project, which has provided sustainable income for 44 low-income families, along with eight new water wells in four villages.

“When a family receives a Biosand Filter, they also participate in health education training related to safe drinking water, how to use the Biosand Filter, and instructions related to installation and maintenance,” shares Kanhchana Thoy, CWEF Cambodia Health Programs Director. CWEF works in partnership with local pastors and village leaders throughout the length of the project, providing these remote communities with life-changing health provisions.

In total, 310 Biosand Water Filters have impacted a total of 2320 people in the Sandan and Chheu Tile communes, serving both families and primary schools. From time to time, the filters need to be renewed and repaired, and this project also restores broken Biosand Filters as needed. We are thankful to share that because your generous gifts, the most acute needs of this remote area have been provided for.


CWEF’s Kanhchana Thoy expresses our gratitude to Pastor Koy Thea in Kampong Thom
Visiting families with Pastor Sareun in Tboung Khmum

Now, our CWEF team in Cambodia is shifting its focus to a new area, again working closely with local church and village leaders. Tboung Khmum province is the location for a newly launched HEAL (“Health Education, Advocacy and Literacy”) project, which includes holistic health education and infrastructure like water wells and Biosand Water Filters.

This community development work will help the “large population of older women, who are taking care of their grandchildren and receiving remittances from their adult children (especially daughters) working in urban areas,” shares Kanhchana. In this area, the average income is between $3 and $4 a day. The health education program, coupled with reliable water wells and Biosand Water Filters, will help “communities live better lives by reducing sickness.”



CWEF anticipates a process of 3-5 years to implement a holistic approach as we equip local health advocates and local families in Tboung Khmum with training and infrastructure.

“This project will have a sustainable impact on many families in Tboung Khmum as we equip them with new knowledge and skills they can use to develop their own communities,” shares Kahnchana.

Thank you! Your support continues to help bring a life-changing renewal of health and hope to families in rural Cambodia.

Health is Priceless

The rising costs of health care is a common concern in the West. People often take for granted the infrastructures and systems that automatically provide sanitary conditions and safe drinking water. Imagine what life is like for people, without health insurance, who are ill on a regular basis by simply drinking (unsafe) water.

Sambo and his wife, Ku, are 25-year-old farmers in the Sandan District of Kampong Thom Province in Cambodia. With a 7th grade education, Sambo makes a living by working the land on farms owned by others. But frequent diarrhea and abdominal pains not only kept Sambo from working; his chronic illness also incurred many medical bills for treatment. The whole family was ill and needed to borrow money just to cover their daily living expenses. The burden was very heavy on Sambo—how to provide for his family and pay the bills? Plus, all the while, they and their young son were struggling with poor health.

Using water from a well and collecting rainwater met their daily needs for washing clothes, cooking, and drinking. Ku believed that the rainwater was clean and was safe to use. However, the family was actually suffering from water-borne illnesses. In 2019, their lives dramatically improved after they decided to participate in a Biosand Water Filter and health training program facilitated by the local church and made possible by your generous donations to CWEF.

Sambo shares, “I regularly bottle the water from the filter and take it to the fields when I work, and I drink a lot of water before I go fishing on the river. All of my family members and I got healthier, and I hope that in the future my family’s living condition will continue to get better.”

Sambo now has enough time and energy to farm and provide for his family’s expenses. Not only are they healthy now—without abdominal pains and diarrhea—but they no longer need to spend so much money on medical treatments. Sambo and Ku can even begin to save money for their family’s future.

Here’s Sambo’s final word to you:

“Now, I am very happy after getting a Biosand Filter from Concordia Welfare & Education Foundation. Thank you for your donations to support my family’s living situation!”
