Who else can travel to Japan except Xu Fu in the Qin Dynasty?

There is no chui fook in history. But in the Qin Dynasty, especially at the end of the war and the end of the Eastern Han Dynasty, many people did move from China to Japan. Among these people, in order to make it easier for them to survive in Japan, some pretend to be descendants of the royal family, and some are quite famous and recorded in Japanese history, such as Gong Yuejun, a descendant of Qin Shihuang, and Liu, the great-grandson of Han Xiandi.
