In his "Daoyi Zhilüe" (1349), Wang Dayuan clearly used "Liuqiu" as a name for Taiwan or the part of it near to Penghu. In "Liuqui Guo Zhilue", it was identified as Ryukyu with specific reference to an island of Gumishan (Kume Island) ruled by a Gumi chief. This text also described this area around 1644 as under strict control of the Japanese shogunate - which is true for the Ryukyu Kingdom (See Invasion of Ryukyu).
