Li Huiyan, of Chongqing, hired 30 villagers for six months to dig the hole in his kitchen, reports IC Media.

He wanted to reach an underground river which he suspected was full of fish.

The river had been over ground but had disappeared 30 years ago when the local authorities bombed part of a mountain to pave a road.

Li explained: “The river used to have so many fish, and by simply putting a net there, hundreds of fish would be caught.”

After digging his pit down to the river, Li installed a fishing net across it and regularly hauls out fish, so far earning his family nearly £2,000.

“I sell the fish at a wholesale price of 24 yuan (£2.15p) per kilo, but 36 yuan (£3.20p) per kilo for retail,” he said.

Li built ladders from his kitchen to the river 16 metres below, and each day he has to go down to check the harvest.
