The earliest record of Xu Fudong crossing the river is Sima Qian's Historical Records. The story of Xu Fu and Qin Shihuang is recorded in The Biography of Qin Shihuang: Xu Fu, a native of Qilu, wrote to Qin Shihuang that there are three sacred mountains overseas, Penglai, Abbot and Yingzhou, where immortals live, and asked the emperor to allow Xu Fu to bathe and fast, and to take boys and girls to get fairy medicine for the emperor. Therefore, Qin Shihuang sent Xu Fu and thousands of boys and girls to look for the immortals in the fairy mountain to get the fairy medicine. This is chui fook's first time at sea.
The second time, nine years after the first time, Xu Fu wrote again asking Qin Shihuang to allow him to lead the fleet to start looking for Xianshan again. He told Qin Shihuang that the first attempt to seek immortality failed because he met a big fish and failed because of the obstruction of the big fish, so this time he hoped that the fleet would be equipped with weapons, especially large weapons such as bed crossbows. Qin Shihuang allowed it. So Xu Fu took three thousand virgins and five seeds this time, and went out to sea with the craftsmen.
According to "Chuifu Arrives in Japan", Chuifu passed on civilization to Japan and promoted the rapid development of Japanese society. Therefore, Xu Fu is honored as "the god of agriculture" and "the god of medicine" in Japan. According to the records, we can infer that the place where Trevor landed should be a plain. In the history books of later generations, it has been mentioned many times that Cui Fu went to Japan, and it has also been said that there are ancestral temples or statues dedicated to Cui Fu in some parts of Japan, and even some Japanese themselves consider themselves descendants of Cui Fu.
