The island is 89 kilometers west-northwest of Ulleungdo, South Korea, and 16 1 km southeast of Japan and Xizhi Island.
South Korea calls the island "Dokdo", while European and American countries call it "lee young Cour Rock" (French: Rochers de Liancourt), which originated from lee young Cour in clermont, Vaz Province, Picardy Region, France. Japan calls the island "Bamboo Island" (Japanese name: Bamboo Island/たけしま). 1903 The fishing guide published in Japan calls the island "Yangku Island".
Although South Korea, North Korea and Japan all claim sovereignty over Dokdo, there is no doubt that the control of Zhudao was seized by South Korea in 1952. The San Francisco Peace Treaty, which demarcated the territory of Japan and South Korea after World War II, did not record that Zhudao was a Korean territory. However, then President Lee sent troops to seize Zhudao before the contract came into effect, and forcibly arrested unarmed Japanese fishermen. South Korea claims that on the old map of South Korea, Zhudao is called Yushan Island and marked as Korean territory. However, after comparison, it can be found that Yushan Island should be an affiliated island in the northwest of Yuling Island, and Zhuyu Island conforms to Yushan Island recorded in Korean ancient books in terms of appearance and geographical location, unlike Zhudao today. For example, Bamboo Island is composed of two main rocks, but the appearance of Yushan Island recorded in Korean ancient books is a very obvious egg-shaped single island, unlike today's Bamboo Island, and its geographical location is far from today's Bamboo Island. On the other hand, the location and appearance of Zhudao are clearly recorded in Japanese ancient books. After comparison, it is found that the appearance and geographical location of Bamboo Island recorded in Japanese ancient books are quite consistent with today's Bamboo Island. In Japanese ancient books, Zhudao is indeed a series of islands composed of two reefs.
