During the surgery, Ma asked the local doctors to stand by his side and explained every detail of the procedure to them carefully.

"Local patients can benefit from the surgeries, but what is more important for us is to train doctors working at the primary level," Ma says. "Only when local doctors grasp the skills can the health of local residents be truly improved."

Another group of volunteer doctors camped near the Xiaoxiang health center in Nangqian county where a boarding primary school of more than 200 students is located.

Due to the high altitude and hypoxia, the incidence of congenital heart disease among children here is significantly higher than in other parts of the country. The volunteer doctors decided to conduct physical examinations for students free of charge.

Six cases of congenital heart disease, three cases of myocarditis and seven cases of sinus tachycardia and sinus arrhythmia were detected among the students during the health checkup.

During their six-day campaign, the team also set up six expert workstations for volunteer doctors at the county level in Yushu and donated more than 2,200 boxes of medicines.

Founded in 2017, China Medical Volunteers aims to help vulnerable patients, support the construction of medical institutions in less developed areas, and promote medical aid work in foreign countries. To date, it has 5,000 medical staff members registered as volunteers.

"The healthcare awareness in plateau areas needs further improvement, especially among women and children," says Nyima Denchou, head of the Yushu maternal and pediatric hospital. "The volunteer doctors have helped tackle the urgent needs of Tibetan people."
