Story:
Towards the end of the Qin Dynasty, Han Xin went to join Liu Bang and was assigned a minor official position managing provisions.
When Liu Bang broke camp to prepare to move to his fiefdom in Hanzhong, many officers secretly fled. Han Xin also seized the opportunity to escape.
Xiao He, upon learning of this, rushed to pursue him overnight without even informing Liu Bang.
Liu Bang, finding Xiao He absent, felt perplexed, as he regarded Xiao He as indispensable, like his left and right hands.
Two days later, Xiao He successfully brought Han Xin back.
