Chasing Han Xin by moonlight
Unused in Liu Bang’s army, Han Xin fled. Hearing of it, Xiao He gave chase himself that very night with no time to report. Someone told Liu Bang "the chancellor has fled," and Liu Bang raged as if he had lost his right hand. Two days later Xiao He returned and said he had gone after Han Xin. Liu Bang cursed him: dozens of generals have fled and you chased none, yet you chase one Han Xin? Xiao He answered, "Generals are easy to find, but a man like Han Xin is a peerless talent of the state." So Liu Bang fasted, built an altar, and made Han Xin his supreme commander.
Sullying himself to survive
In his later years, while away suppressing revolts, Liu Bang repeatedly sent messengers to ask "what is the chancellor doing?" A retainer warned Xiao He: your rank is at the summit and you hold the people’s hearts — the emperor is testing you. So Xiao He forced the purchase of people’s land and lent at interest, deliberately ruining his own reputation. When Liu Bang returned, the people blocked the road to accuse the chancellor, and Liu Bang laughed and was at ease. A meritorious minister trading his good name for his ruler’s peace of mind — the cruelty of early Han politics is laid bare in this detail.
