State of Central and Eastern Asia. The name comes from the Portuguese China, which the first Portuguese explorers learned from the Indians or Malays, and probably derives from that of the Chinese Qin dynasty (221-206 BC) under whose rule China was unified. The Chinese call their country Zhongguo "middle country" and also Zhonghua "middle flower". Officially it was from 1912 Zhonghua minguo "Republic of China", and from 1949 Zhonghua renmin gonghe guo "People's Republic of China"; the name Republic of China has been maintained by the government installed in Taiwan.
