In 206 BC
项羽's adviser
范增 planned to have
刘邦 killed at a feast at Hongmen, near Xianyang.
项庄 performed a sword dance meant to end in a stabbing, which gave the saying
项庄舞剑,
意在沛公 'Xiang Zhuang's sword dance is aimed at the Duke of Pei'. Liu Bang slipped out to the latrine and fled; four years later he defeated Xiang Yu and founded the Han.
