In the early years of Shunzhi, Li Hei, a bandit from Luliang, could not bear to rob the old and weak and joined Shanxi merchant Zhang Jingming. He relied on his vigilance in his gangster career to protect trade routes, and resolved trade disputes between Mongolia and Han with sincerity, and emerged in the internal strife between Shanxi merchants and the game between government and businessmen. From an apprentice to a leader of Shanxi merchants, Li Hei took "integrity as the basis and family and country as the root" and created a business legend in troubled times.
