 The quick collapse of the Liao led to more negotiations between the Song and the Jin . Jurchen military success and their effective control over the Sixteen Prefectures gave them more leverage . Aguda grew increasingly frustrated as he realized that despite their military failures the Song still intended to seize most of the prefectures . In the spring of 1123 the two sides finally set the terms of the first Song – Jin treaty . Only seven prefectures ( including Yanjing ) would be returned to the Song , and the Song would pay an annual indemnity of 300 @,@ 000 packs of silk and 200 @,@ 000 taels of silver to the Jin , as well as a one @-@ time payment of one million strings of copper coins to compensate the Jurchens for the tax revenue they would have earned had they not returned the prefectures . In May 1123 Tong Guan and the Song armies entered the looted Yanjing .
