The Battle of Yancheng (simplified Chinese: 郾城之战; traditional Chinese: 郾城之戰) took place in 1140 near modern-day Luohe City in Henan Province, China between the main armies of China under the Song dynasty and the Jurchen or Jin invaders from the north. The battle was a major clash in the wars between the Jin Empire and China. The Chinese forces, under the leadership of General Yue Fei, won a decisive victory despite being outnumbered.
Yue is supposedly associated with xingyi.
