Yelü Yilie

History of Liao states he changed his era name to Shaoxing in 1151, however recent coins unearthed in Central Asia might prove it was a scribal mistake.

[4] The same year Karluks under Ayyar Beg revolted against Western Karakhanid ruler Ibrahim III and killed him.

Chagri marched on Ayyar Beg with reinforcements from Qara Khitai and eastern Karakhanid Ibrahim II[5] (who was created Ilig Türkmen by Yelü Dashi[6]).

In 1158, Yelü Yilie ordered expulsion of Karluks from Bukhara and Samarqand to Kashgar and charged Chaghri to deal with matter.

Chaghri just had reinforcements from new East Karakhanid ruler Muhammed II consisting of 10,000 men, while Karluks marched on Bukhara with Khwarazmi help.
