After leaving his home, Mr Wang dropped his 'trash' off at a public waste collection point, only to reach the bank later and realise his mistake.
When he rushed back to the dump, he was unable to find his bag. Mr Wang then called the police.
Officers checked CCTV footage from the area to discover someone walking away from the dump with the bag full of money. However, the unclear and grainy pictures were not of much help.
Luckily for Mr Wang, though, the person who discovered the bag full of money turned out to be a woman who came forward after seeing police's appeal for help or information. This is how his money was returned to him.
"I couldn't sleep well after finding such a big sum of money," said the woman, according to South China Morning Post.
