Wu Zhengrong and his wife Du Xuehui, both 41, from Stuttgart, Germany, have lived in Changsha City, capital of central China's Hunan Province for 10 years.

Last year, they opened Bach's Bakery on Xiangchuxiang Road. What makes it special is that the cashier and bakers are hearing- and speech-impaired people. Wu and Du teach them to make German bread, helping them become self-sufficient.

"They learn it quickly and can make tasty bread. I hope they can work here if they are willing to," Wu said.

Before the couple came to China, they had heard that many children from poor families became hearing-impaired due to delayed treatment of childhood illnesses. Fond of Chinese culture, they joined a language training program for hearing-impaired Chinese children attached to a German charity organization.

At first, they trained children on their language skills for the Hunan Disabled Persons' Federation. Later, they expanded their volunteering scope to other therapy centers.

"Within Hunan Province, our program has financially supported more than 80 kids. We go to each therapy center twice a semester," Du said.

Ten years ago, they had heard of Lei Feng, a Chinese altruist remembered yearly on March 5. "He was a great person. My birthday is on Lei Feng's Day. Everyone should do something to help others, just like Lei," Wu noted.
