The name China is recorded in English from the mid 16th century. It is of uncertain origin, but likely derived from Middle Persian after the Qin dynasty. In Chinese, common names for China include Zhongguo (中國/中国) and Zhonghua (中華/中华), while Han (漢/汉) and Tang (唐) are common names given for the Chinese ethnicity. Other names include Huaxia (華夏/华夏), Shenzhou (神州) and Jiuzhou (九州). The People's Republic of China (Zhōnghuá Rénmín Gònghéguó) and Republic of China (Zhōnghuá Mínguó) are the official names for the two contemporary sovereign states currently claiming sovereignty over the traditional area of China. "Mainland China" is used to refer to areas under the jurisdiction by the PRC usually excluding Hong Kong and Macau.
There are also names for China based on a certain ethnic group other than Han; examples include "Cathay" based on the Khitan and "Tabgach" based on the Tuoba.
In mainland China, the term Zhongguo is used to refer to all territories claimed by the PRC, including mainland China, Hong Kong, Macau and Taiwan.
