Kumo Xi
The Kumo Xi were completely integrated into Khitan administration by 997. The prior arrangement of vassalage and tribute had lasted since the time of Emperor Taizong of Liao, but a series of reforms between 994 and 997 discontinued that role. The Kumo Xi king became a salaried official and Chinese style administrative units were set up in Kumo Xi territory. Their former capital became the "Central Capital" (Zhongjing), which received an inner and outer wall, a Confucian temple, and public buildings were constructed between 1018 and 1020.
