Dachanghe
# Dachanghe

Dachanghe (Chinese: 大長和; lit. 'Great Long Harmony'), possibly Da Changhe or Changhe, was a monarchy from 902 to 928 in modern Yunnan, China. Founded by Zheng Maisi (鄭買嗣), it was the successor state of Nanzhao (738–902), whose ruling Meng (蒙) family was mass-murdered in a bloody coup by Zheng. The Zheng family suffered a similar fate 26 years later at the hands of Yang Ganzhen (楊干貞), who helped found a state named Datianxing (大天興) (928–929).

Dachanghe bordered Former Shu to its north.
