Gao Wenqi, 49, owner of a restaurant in Xi'an, Shanxi, started to offer a new service on April 13, 2013: suspended meals (待用快餐). Now many restaurants in China, such as in Henan,Chongqing and Yunnan, have joined the program.

You can pay 10 yuan for a meal, which should be sold at 16, and leave it at the restaurant. Then other people in need, such as the disabled（残疾人）， the poor elderly or homeless children,can have it without paying.

This idea comes from the cafes (咖啡馆) in Naples, Italy. It's a tradition that someone there pays in advance for an extra (额外的) cup or two. Then another coffee-drinker can take them for free.

“The program is meaningful. It offers help with dignity（尊严），” said Gao to Xinhua. However, people are worried that someone who is able to pay would also ask for the suspended meals, so there should be rules for this program.
