韩世忠
The move of the Song capital south to Hangzhou signaled the transition from the Northern Song era to the Southern Song. Qinzong's younger brother, Prince Zhao Gou, was enthroned as Qinzong's successor in the southern capital in 1127. Zhao is known posthumously as Emperor Song Gaozong. The Jin general Wuzhu crossed the Yangzi River in 1130 and tried to capture Gaozong, but the Emperor escaped. Wuzhu retreated north across the Yangzi, where he fought off a stronger Song fleet commanded by Han Shizhong.
