Is the story of eunuch Yao Xun true? From what information?

This is a lie, a lie fabricated by comprador, for the following reasons:

1, the Qing dynasty had strict restrictions on eunuchs, and they were not allowed to speak or act without authorization, and they were not allowed to stay away from Miyagi;

2. There is an example of castrating a boy to become a member of a choir in a Catholic church in France and Italy. The Frenchman is looking for a cigarette himself.
