The man's name is Fat Sun, and there is a gold silkworm method. In Phoenix Mountain, the title of the book is four words. I forget what it's called. Who knows?

The witch doctor who learned a skill secretly told Sun Dawei to go down the mountain to join the WTO. He has no great ambitions. He just wants his family to be healthy and happy. He can save lives and make some money. But he never expected to find himself, facing all kinds of temptations and entanglements in the world, watching a fat man dress up as a pig and eat a tiger to carry forward witch doctors.
