The earliest written records about people in Japan are from Chinese sources from this period. Wo, the pronunciation of an early Chinese name for Japan, was mentioned in 57 AD; the Na state of Wo received a golden seal from the Emperor Guangwu of the Later Han dynasty. This event was recorded in the "Book of the Later Han" compiled by Fan Ye in the 5th century. The seal itself was discovered in northern Kyūshū in the 18th century. Wo was also mentioned in 257 in the "Wei zhi", a section of the "Records of the Three Kingdoms" compiled by the 3rd-century scholar Chen Shou.
