The new triangular arrangement between the Southern Song, Jin, and Western Xia continued the age of division and conflict in China. The region of Huainan (between the Yangzi and Huai rivers) became a new borderland and battleground between Song and Jin from 1128 to 1141, displacing hundreds of thousands of families who had lived there for generations. The Southern Song deployed several military commanders, among them Yue Fei and Han Shizhong, to resist the Jin as well as recapture territory, which proved successful at times. Yue Fei in particular had been preparing to recapture Kaifeng (or Bianjing as the city was known during the Song period), the former capital of the Song dynasty and the then southern capital of the Jin, after a streak of uninterrupted military victories.
