耶律大石
In the spring of 1122, the Liao court rallied around Prince Yelü Chun and made him emperor in Nanjing. Yelü Chun rebuffed the Song appeals to surrender. In May, the Song commander Tong Guan sent two armies to capture Nanjing, but Zhong Shidao's eastern army was defeated by Yelü Dashi at Baigou (in Rongcheng County, Hebei) and Xin Xingzong's western army was driven back by Xiao Gan at Fancun (in modern Zhuozhou, Hebei).
