Even though in Mandarin Chinese China is called Zhōngguó, meaning the "Middle Kingdom" or the "Central States", most other countries calls it China. It is believed that the word China cam from the word Qín, in which the Qin dynasty unified China. However, there are a few exceptions. In Japanese, it is called Chūgoku, which has the same meaning as the Chinese name, except it uses the Japanese pronunciation for the Chinese characters for the name 中國 / 中国.
