How do you say "Yellow Emperor" in English?

The "emperor" of "Yellow Emperor" does not mean "emperor", but "emperor" of "three emperors and five emperors", which is an ancient honorific title. After the Qin Dynasty unified China, the emperor and the emperor were combined into one, and the ruler was called "Emperor" with a new honorific title. In ancient times, "Emperor" and "Emperor" were both separate titles and could not be interpreted as "Emperor". Moreover, "Yellow Emperor" is people's honorific title for Xuanyuan, but "Yellow" does not mean "Yellow". "Yellow Emperor" is a fixed title, and the two words cannot be separated. Therefore, transliteration and translation into English are "Yellow Emperor".
