in different European languages. Chinese names China developed and adopted the Pinyin romanisation system in February 1958 in place of previous systems such as the postal romanization and Wade–Giles. Many Chinese geographical entities (and associated entities named after geographical names) thus had their English names changed. The changes sometimes appear drastic, since it is sometimes the case that the former romanisations were derived from Cantonese—the common language in British-held Hong Kong—while the newer romanisations are derived entirely from Mandarin. However, the pronunciation in Mandarin has mostly stayed the same both before and after the change. Pinyin was adopted by the International Organization for Standardization in 1982 and officially adopted in Singapore (resulting in several geographical name changes of its own). However it is usually not applied in the autonomous regions of the PRC (e.g. Lhasa, Ürümqi, Hohhot, Xigazê, Ili, Altay, Kaxgar, Hulunbuir, Erenhot, with a notable exception being place names in Ningxia, whose native Hui people speak Mandarin as their native language) and has not resulted in any geographical name change in the SARs of Hong Kong and Macau, and is adopted only in parts of Taiwan, particularly within Taipei and other Kuomintang controlled cities and counties, in a recent push to adopt Pinyin by the Kuomintang government. Examples of changes: In the People's Republic of China Peking → Beijing Canton → Guangdong Nanking → Nanjing Sian → Xi'an Chengtu → Chengdu Chungking → Chongqing Tientsin → Tianjin Sinkiang → Xinjiang Heilungkiang → Heilongjiang In the Republic of China (Taiwan) Shih-lin → Shilin Chung-cheng → Zhongzheng Tamsui → Danshui (since reverted) In Singapore Peck San → Bishan Ao Kang → Hougang Nee Soon → Yishun Korean names The introduction of the Revised Romanization of Korean in place of the McCune–Reischauer system on 7 July 2000 by the South Korean government has resulted in a string of changes to geographical names. The system is not used by North Korea. Examples of changes include: Inchŏn → Incheon Kyŏngju → Gyeongju Pusan → Busan Taegu → Daegu Taejŏn → Daejeon Exonyms and endonyms For geographical entities with multiple pre-existing names in one or more languages, an exonym or endonym may gradually be substituted and used in the English language. Many countries have intentionally had their common English names officially changed to the local name, such as Côte d'Ivoire and Timor-Leste's translations to their local languages, or Persia requesting to be known by the
