Is the succession ceremony of the ancient emperor held at the same time, or can the ceremony be held after the succession?

After the death of the old emperor, the prince or the designated heir will immediately become the emperor, and at the same time mourn for the first emperor. The exact interval of the enthronement ceremony is within one month after the death of the old emperor. There are great differences between dynasties, and the Han Dynasty usually has to wait about a month. In the Tang and Song Dynasties, the ceremony of accession to the throne was often held on the second day after the death of the first emperor, while in the Ming and Qing Dynasties, it was often held about half a month (Kangxi was special, and the ceremony of accession to the throne was held on the third day after the death of Shunzhi).

However, in ancient times, in most cases, when the old emperor died, the next generation of emperors and ministers would be around. When the old emperor dies, ministers will immediately pay homage to the new emperor, which is actually considered succession; After the death of the first emperor, the new emperor (although the enthronement ceremony has not yet been held) will still be called the emperor by ministers. After the enthronement ceremony, he will become a justified emperor.

Generally speaking, the ceremonies of succession and accession to the throne were mainly held in Han Dynasty, Ming Dynasty and Qing Dynasty, and most of them were held at the same time in Southern and Northern Dynasties, Tang Dynasty and Song Dynasty.
