I mean: people who have not done enough in morality, ancient monarchs and princes are modest names for themselves. In ancient China, it was emphasized that "ruling the country by virtue" and "matching heaven with virtue", that is to say, the power of monarchs and vassals was endowed by heaven, but God only gave the world to virtuous people, and monarchs and vassals would lose their noble power if they lost their virtue, so monarchs and vassals called themselves "widows" modestly.

"Wei Zhou tries to see the old country" points out that the noun of monarch in ancient Chinese contains the initial sound of *ko-/*kw-. He believes that the ancient emperors and princes claimed to be lonely, widowed and ignorant, perhaps because their sounds were similar to "Jun".

In ancient times, the wives of princes also claimed to be widowed, and the poem "The Great Wind" said: "I am grateful to you first, so that I can be widowed." This is Wei Zhuanggong's wife, Zhuang Jiang, calling herself. From the Han Dynasty to the Five Dynasties, it was also called this. When Liu Bang was the king of Hanwang, Han Xin was the king of Qi, Emperor Yangdi was the king of Jin, and Liu _ was welcomed in the later Han Dynasty, all of them claimed to be widowed, but the fashion in Han Dynasty was more common than that in later Han Dynasty.

Zhao Yi, a scholar in the Qing Dynasty, investigated the use of "I am a widow" in history: in the Spring and Autumn Period, governors called themselves I am a widow, but kings of Chu mostly called themselves "Bu Gu". The weaker princes called themselves "orphans". Although the Seven Heroes of the Warring States arrogantly claimed to be the king, they still claimed to be "I am the only one" instead of "giving one person" dedicated by the Zhou Emperor.

The ancient monarchs in China were divided into emperors and kings. Since Qin Shihuang, the emperors used the word "I" that everyone could call themselves as the proper name of the emperor, but no one but the emperor could use it. Kings are different. In ancient China, kings were not called "I", but "I", "I'm lonely" and "I don't have a hub".
