It’s not about the prince’s name. In ancient times, the emperor’s name was mainly taboo. The emperor must change his name after he ascends the throne, otherwise he will be beheaded.
There is actually an example in history:
Among the founding heroes of the Tang Dynasty were Guanglu Dafu, Minister of the Ministry of War, and British Duke Xu Shiji
Li Ji (594-669) His original surname was Xu, his given name was Shiji, and his courtesy name was Maogong (also known as Maogong). He was of Han nationality, from Lihu, Caozhou (today's Dongming area in Shandong Province), and was a politician and military strategist in the Tang Dynasty. Because Li Yuan, the emperor of the Tang Dynasty, gave him the surname Li, he was named Li Shiji. Later, to avoid being tabooed by Emperor Taizong Li Shimin of the Tang Dynasty, it was changed to a single name.
He was named the British Duke and was one of the twenty-four heroes of Lingyan Pavilion. In the Tang Dynasty and even in the history of China, Li Ji can be said to be a very legendary figure.
He was a general and a prime minister, ranked among the three nobles, and displayed all the glory in the world. It went through the three dynasties of Tang Gaozu, Tang Taizong and Tang Gaozong (Li Zhi).
When Taizong was dying, because Prince Li Zhi was not kind to Li Shiji, he deliberately demoted him to the governor of Diezhou. After Li Zhi came to the throne, he promoted Li Shiji to Shangshu Zuopushe. He won the trust and responsibility of the imperial court and was relied upon as the Great Wall by the imperial court.
After the death of Emperor Gaozong of the Tang Dynasty, Empress Wu came to the court and deposed Emperor Li at will, and massacred the Li Tang clan. The high-ranking officials of the Wu family were given more power, and the world was full of resentment. It happened that Li Ji's grandson Li Jingye and his two brothers were demoted because of corruption. In Yangzhou, they met Tang Zhiqi, King Luo Bin and others who were also demoted. Several people took the opportunity to start an uprising in Yangzhou. In ten days, more than 100,000 soldiers were victorious. .
After Li Jingye was appointed, Wu Zetian issued an edict to hunt down Li Jingye’s ancestor and father’s official rank, create a tomb and cut the coffin, and restore the original Xu family.
