“I can eat a lot - is that a fault?” he said, adding that he didn’t waste any of the food.
But the restaurant owner told the same reporter that Mr Kang was causing the restaurant to lose money.
“Every time he comes here, I lose a few hundred yuan,” he said.
“Even when he drinks soy milk, he can drink 20 or 30 bottles. When he eats the pork trotters, he consumes the whole tray of them. And for prawns, usually people use tongs to pick them up, he uses a tray to take them all.”
He added that he is banning all live-streamers from the restaurant.
The story is trending on Chinese social media and has racked up more than 250 million views on Weibo.
Some people think he is a hero while others sympathise with the restaurant.
Regardless of who you side with - there’s no denying that putting away 4kg of prawns in one go is pretty impressive.
