Wanyan Xiyin

Gushen (died 1140), also known as Wushi or Hushe, and better known by his sinicised name Wanyan Xiyin, was a Jurchen noble and civil minister who lived in the founding and early years of the Jurchen-led Jin dynasty (1115–1234), which ruled northern China between the 12th and 13th centuries. He was a chief adviser to Aguda (Emperor Taizu), the founder and first emperor of the Jin dynasty. Described by modern writers as the "Chief Shaman" of the pre-Jin Jurchen state,^[1] he became deeply interested in Han Chinese culture, and is particularly known as the creator of the first writing system for the Jurchen language.
