The first month is also called Duanyue to avoid Qin Shihuang's anonymity.

Yes, the end, and the top also means the beginning. The end of the month refers to the first lunar month, and the beginning of the year is positive. The first month of the lunar calendar is a month with many traditional festivals. Such as the Spring Festival on the first day of the first month, the second day of the first month, the fifth day of the first month, the God of Wealth, and the Lantern Festival on the fifteenth day of the first month. Textual research on "Duanyue" in Historical Records says that it is because Qin Shihuang was born in Zhao in the first month and was named "(Zhao Zheng)". Therefore, after Qin Shihuang became the king of Qin, his subjects renamed the first month Duanyue in order to avoid taboo.
