Xu Chu, courtesy name Zhongkang, was a Chinese military general who lived during the late Eastern Han dynasty and the Three Kingdoms period of China. He started his career as a bodyguard to the warlord Cao Cao and later became a general in the state of Wei during the Three Kingdoms period. He was described to be a big and strong man, yet simple minded and honest, so he was nicknamed "Tiger Fool" by his men. After his death, he was posthumously honoured with the title "Marquis Zhuang", which literally means "robust marquis".

Fan Kuai was a military general of the early Western Han dynasty. He was a prominent figure of the Chu–Han Contention, a power struggle for supremacy over China between the Han dynasty's founder, Liu Bang, and his rival, Xiang Yu.
