When it comes to a product, there should be a lot of coatings, especially for indoor offices. Because it is directly under the jurisdiction of the emperor, there are many families, such as:
The surname is Feng, from Huangqi, the Ministry of Internal Affairs. He is a university official, and his granddaughter married Xiao Shenyang.
Official document, surnamed Wang, is from Zhengbaiqi, the Ministry of Internal Affairs (later carried into Zhengbaiqi, Manchuria), and official document is a university student. He was awarded the first-class count for suppressing Taiping Army and Nian Army.
Lai Bao: Sitara, a native of Zhengbaiqi, is an official of the Criminal Department of the Ministry of Internal Affairs.
In addition, there are many positions as commanders of guards, such as ministers in charge of guards, and ministers in charge, such as Tong Nami and Guo Mai.
However, it seems that I have never heard of the coating of the next five flags as a product.
