Why did the eunuch (owner of the East Factory) in ancient times have to be called nine thousand years old?
Only Wei Zhongxian, the eunuch in history, was called "when he was nine years old, he used the dispute of three cases and the prison of Xiong Tingbi to make his followers take the opportunity to attack honest ministers. Wang Wenyan, Zhao Nanxing, Yang Lian and Gao Panlong were killed or sent to the garrison, and his party was placed in Jin Yao again and again. Flatterers actually called him "Nine Thousand Years Old", and local governors built shrines for him to worship. When he ascended the throne in four cases, he found his traitor and ordered his arrest, but he hanged himself. In the second year of Chongzhen (1629), the case was lost and most of its party membership was expelled.
