Xu Fu's deeds were first seen in Biography of Qin Shihuang and Biography of Hengshan in Historical Records (called "Xu" in Biography of Qin Shihuang and "Xu Fu" in Biography of Hengshan in Huainan). According to historical records, Qin Shihuang hoped to live forever. In 2 19 BC, Xu wrote that there were three fairy mountains in the sea, Penglai, abbot and Yingzhou, where immortals lived. So Qin Shihuang sent Xu Shiling to lead thousands of boys and girls, as well as three years of food, clothing, shoes, socks, medicines and farm tools to seek immortality in the sea, which cost a lot of money. However, Xu led many people to the sea for several years and did not find the holy mountain. In 2 10 BC, Qin Shihuang traveled eastward. Xu explained that he was blocked by huge mackerel after going out to sea and could not sail. He asked more shooters to deal with mackerel. Qin Shihuang agreed and sent a shooter to shoot a big fish. Later, Chui Fu led many people to the sea and came to the "Guangze Plain" (probably Kyushu, Japan). He felt that the local climate was warm, the scenery was beautiful, and the people were friendly, so he stopped being king and taught the local people the methods of farming, fishing, whaling and paper arrangement, and never came back.
Later, history books recorded that Xu Fu went to sea, but there were different opinions about where he went. The reflection "Wu Shu? Biography of Wu Sovereignty, History of the Later Han Dynasty, Biography of Dongyi and Biography of Kuodi are all recorded as, but the specific location is unknown. In the last week of the Five Dynasties, the monk Yi Chu wrote "City Wall" in the Six Sticks of Yi Chu. "Japan" explicitly mentions for the first time that Xu Fu finally arrived in Japan, which is today's Qin family (an ancient Japanese ferry family. ) is his descendant, and said that after Xu Fu arrived, it was called Mount Fuji Penglai.
