After Liu Bang's death, filial piety Hui Di Liu Ying acceded to the throne.
Therefore, Liu Bang has descendants. There are many people surnamed Liu now, and some of them should be descendants of Liu Bang. According to rough statistics, the royal family in the Han Dynasty gave birth to many descendants, so that most of Liu's surnames came from the royal family at the end of the Han Dynasty, and Liu's large-scale surname change was not very severe, so now most of Liu's surnames should be his descendants, and if matriarchal inheritance is counted, many Li's surnames are also after Liu Bang, because Li Yuan's grandfather is a descendant of Liu Bang, so there are many descendants of Liu Bang.
It can even be said that there is no ancestor surnamed Liu and Li on his ancestors, which is conceivable.
