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.
