There was a minister named Qi Huangong in the State of Qi. What was his name? Is it a king or an emperor or something?

In the period, only Zhou Tianzi could be king, and the princes called Zhou Tianzi an intruder. Therefore, Qi Huangong cannot be called king. It was only after Qin Shihuang confirmed the word "emperor" that the emperor gradually began to be called the emperor, so it was impossible to be called Qi Huangong.

During the Spring and Autumn Period, courtiers called princes "kings", and Historical Records/Duke Family of Lu Zhou mentioned that "the people are kings, and the monarch stands. I asked you to kill your son, and you took me as your phase. " Therefore, if a minister calls Qi Huangong, it should be Lord or Lord.
