Chen Yingbo is a doctor committed to the health and well-being of Chinese people.
He's been providing free diagnosis and treatment to his patients for 16 years.
Every Thursday night Chen makes himself available to treat sick people despite being retired for more than a decade.
He said he's been studying traditional Chinese medicine for 56 years.
"At the beginning of the country's reform and opening up in the late 1980s, it appeared people were only concerned about money," he said.
"No one was interested in offering help for nothing."
"As a doctor, helping people in need is our basic duty and it has nothing to do with money."
Chen then proposed to set up a free clinic.
In 1988, with the help of the Fengxian Overseas Chinese Affairs Office, the clinic was established and opened once a week.
Local doctors and nurses immediately volunteered their services.
Over the past 16 years, nearly 40 doctors have been part of the team ensuring the continuation of the free medical service.
Chen said in the early days the clinic was in poor condition.
"Fortunately, we have received all kinds of help from the local health bureau and hospitals," he said.
"We've even received assistance from schools and clothing factories."
"We could not have run successfully without their help," he said.
The clinic mainly offers patients traditional Chinese acupuncture and massage treatment.
About 21,000 people have been treated at the clinic.
"Before I came to the clinic I had been feeling uncomfortable for years," said Xiang Hua, a local resident.
"I had been to various hospitals for different checks, but none of the reports showed anything wrong."
"It was Doctor Chen who told me that I was deficient in vital energy."
"I felt much better after taking the herbs that he prescribed to me," he said.
Residents from nearby districts, such as Jinshan and Songjiang, have also come to the clinic for help after learning they could receive free treatment.
One patient even wrote a letter to Chen asking about his chronic disease after he heard about the clinic on a radio program.
The 74-year-old doctor wrote back to him immediately.
"He wouldn't let us write the letter for him," said Cao Lin, the team leader and doctor from Fengxian Guhua Hospital.
Chen has encouraged his daughter Chen Yue, also a herb doctor, to join the team.
"I'm glad to see that young doctors have realized the importance of helping people and don't ask for anything in return," Chen said.
"This is what a true doctor should do. It is also the main reason why we opened the clinic."
"We will probably continue our work to spread love and care to the society," the doctor added.
