Recently, a small heart-warming gesture went viral on the Chinese internet. After a team of firefighters from Ganzhou, Jiangxi Province, completed a rescue mission, they went to a restaurant for dinner. But when the firefighters wanted to pay for their meals, they were surprised to find out that four young people had quietly paid for them. In fact, such heart-warming gestures can be found everywhere in the Chinese society. Giving and receiving always work both ways. Reciprocity is an important part of the Chinese culture. Behind every city, there are people guarding ordinary citizens as "unsung heroes." They deserve the acts of kindness, gratitude and respect from ordinary people for their contribution to society.
