Crayfish 'comes back to life' in diner's dish in China

A cooked crayfish startled a diner after it began moving across their dish at a restaurant in northern China. 

The video, shot in the city of Yuncheng in Shanxi Province on July 13, shows a cooked crayfish suddenly starting to move around a bowl. 

According to the customer, he ordered a portion of spicy crayfish in a barbecue restaurant. 

However, a crayfish suddenly started to move in the bowl when they already ate half of the dish. 

The customers said they did not know why the crayfish "came back to life" but they thought it was interesting.
