China (i//; Chinese: 中国; pinyin: Zhōngguó), officially the People's Republic of China, is a sovereign state located in East Asia. It is the world's most populous country, with a population of over 1.35 billion. The PRC is a single-party state governed by the Communist Party, with its seat of government in the capital city of Beijing. It exercises jurisdiction over 22 provinces, five autonomous regions, four direct-controlled municipalities (Beijing, Tianjin, Shanghai, and Chongqing), and two mostly self-governing special administrative regions (Hong Kong and Macau). The PRC also claims Taiwan – which is controlled by the Republic of China (ROC), a separate political entity – as its 23rd province, a claim which is controversial due to the complex political status of Taiwan.
Yuanyang County (simplified Chinese: 元阳县; traditional Chinese: 元陽縣; pinyin: Yuányáng Xiàn; Hani: Yeiqyaq) is located in Honghe Prefecture, Yunnan province, China, along the Red River. It is well-known for its spectacular rice-paddy terracing. Part of the area now forms the 45th World Heritage Site in China.
