In fact, the ancient emperors of China claimed a lot about themselves. At the beginning of the Zhou Dynasty, the vassal system was implemented, so these vassal states all called themselves solitary. This statement, like me, is a very low-key and humble statement. Later, after Qin Shihuang unified the six countries, Qin Shihuang was very indifferent to the title of me, so he called himself me. Since then, many emperors have always called themselves me. As we all know, ancient emperors had the titles of son of heaven, your majesty and emperor's holiness. These titles were also used in some formal occasions, and there were some other titles in some informal occasions. For example, the emperor of Han Dynasty would be called a county magistrate, the emperor of Sui Dynasty would be known as everyone, and the emperor of Song Dynasty would be known as a butler.
Looking at the appellations of ancient emperors in China, we will find that the appellations of ancient emperors are actually varied, and they also have different tendencies in different dynasties. For example, before the Tang Dynasty, most emperors were called by posthumous title plus the emperor's title, while the emperors from the Tang Dynasty to the Yuan Dynasty were called by the temple name, and the emperors after the Ming Dynasty were mostly called by the year name. Because the emperor is the highest ruler in the feudal dynasty, he can't call the emperor by his first name, so he has a substitute name for these emperors, such as temple number, respect number and year number, such as Emperor Wu of Han Dynasty, Emperor Han Guang, Emperor Wen of Han Dynasty, Emperor Xiao Zong of Ming Dynasty and Tang Zhongzong.
Finally, because of their status, the ancient emperors of China were also very concerned about addressing.
