This article is finally defined as a fantasy novel, and many friends have asked me if it is wrong to write the official title "duke" in the article is an official position in the West.

Thank you for your questions, which are explained here. Although "Duke" is now a translation of the English Duke, it is indeed an official position in ancient China.

Since the pre-Qin era in China, there have been monarchs who have conferred the title of duke, which is the first class of the fifth-class duke in the ancient Chinese feudal system. The royal system of etiquette: "The king's system is the lord of Lu, the prince and the prince, and the fifth class".

However, taking into account the habits of some readers, the position of "Duke" was officially renamed "Taishi"

Thank you again for your support!
