  ## History
  
  The region was historically called Si'en County and Yibei County (宜北县). Si'en County (思恩县) was controlled by the People's Liberation Army (PLA) in November 1949 and came under the jurisdiction of Qingyuan Special District (庆远专区).
  
  In August 1952, Si'en County was revoked and Huanjiang County was set up, which was under the jurisdiction of Yishan Special District (宜山专区). In 1958, its name was changed to Red Flag People's Commune (红旗人民公社) and belonged to Liuzhou Special District (柳州专区). One year later, it split into two communes: Chengguan People's Commune (城管人民公社) and Dacai People's Commune (大才人民公社) and soon merged to form Chengguan District (城管区) in 1962. In May 1965, it came under the jurisdiction of Hechi Special District (河池专区). In 1968, it reverted to its former name of Chengguan People's Commune (城管人民公社). In 1984, it was upgraded to a town named Si'en (思恩镇), which is still in use now.
