"I lifted the fish, and saw it was already rotting. But then a package wrapped in oily paper dropped out. I used a stick to poke the package to make sure it wasn't a prank or something," he told the City Evening.
Wang says that when he saw money inside, he couldn't believe his eyes. The money came to 3,000 yuan, nearly £200.
"The fish must have been given to someone as a present. But I guess they didn't know about the money," he added.
Wang says he will return the money if anyone can correctly identify the colour and other characteristics of the package. Ananova
