Cheng Yanxin, a 70-year-old sanitation worker, lost three months of his salary on Jan. 12. He has since recovered the money, thanks to the help of kind-hearted people.

Cheng planned to use the money for Spring Festival shopping, but later lost track of the cash. Zhao Ping, the manager of a steamed bun shop, generously helped the old man to search for his lost savings. Zhao also shared the story on social media, asking others to look for the envelope of money as well. Just five minutes later, Cheng began receiving calls from people offering to join the search efforts. Within two hours, an envelope with 3,360 RMB was sent to Cheng.

In fact, the money in this envelope, which exactly matched Cheng's lost salary, was not his salary at all but rather donations given by warm-hearted people from 25 provinces.
