It is also called Shizi. During the Zhenguan period of the Tang Dynasty, some people lacked writing for the character "Shi" because they avoided taboos, while others did not avoid taboos and wrote the character directly. For example:
The name is marked in Han Dynasty. (In the fourth year of Zhenguan, the epitaph of Hu Gong's "Quality" was settled)
On the verge of death. (In the fifth year of Zhenguan, the emperor's epitaph was tabooed)
Gonghou Tu attacked and passed on to the prime minister. (In the eighth year of Zhenguan, the epitaph of Li Jun ("Succession"), a virgin)
The seventh grandson of Emperor Yan Zhaocheng. (In the 16th year of Zhenguan, the epitaph of Feng, the wife of Fan Yang, the official official of the Tang Dynasty and Lu Mansion)
These epitaphs and epitaphs reflect the characteristics of the taboo avoidance system in this period that was not very strict: The subjects may or may not avoid the monarch's taboos. Even in the same epitaph, there are some taboos and untaboos coexisting. For example, in the "Zhongzhong Epitaph" written in the 20th year of Zhenguan, there are both "Shizi Wuting" and "Benzhi Bai丗". The former word "Shi" is straightforward, but the latter word "丗" is missing due to taboo.
Tang Taizong was a very enlightened ruler. After he came to the throne, he issued an edict stating that as long as the word "世民" is not used together in words, there is no need to avoid it.
"The order said: "According to etiquette, the two names are not taboo. In modern times, both words have been avoided, and there have been many obsolescences. Acting on one's own will is contrary to the classics. If the official title, personal name, and public and private documents contain the word "Shimin" that is not consecutive, there is no need to conceal it. "(Old Book of Tang·Benji No. 2).
The "Six Ministries" in the six-ministry system of the three provinces in ancient times were originally the six agencies of "officials, people, rituals, soldiers, punishments, and workers". Among them, the "Ministry of the People" was not renamed during the reign of Emperor Taizong of the Tang Dynasty to avoid Li Shimin's word "people". However, after Tang Gaozong Li Zhi came to the throne, in order to show his filial piety and respect, he ordered the "Minbu" to be changed to "Hubu"
