Dishwasher? I'm the King of the Kitchen!

Three years ago he was the leading cook in China, the one people called the god of cooking. His apprentice turned on him and had the tendons in his hand cut, and he went from the kitchen to washing dishes. Three years on, the same apprentice runs a livestream that the whole internet watches and announces that he is going to smash a shop sign that has hung for a hundred years. He closes his right hand, which is cracked from the cold, picks up a rusted cleaver and makes a single cut with it. The chairman of the association kneels in front of him, puts his head to the floor and calls him master, and word of it goes out across the internet. The bowl of cabbage boiled in plain water that he had been laughed at for turns out to be one of the lost dishes of the old Chinese kitchen.
