Ли Цзычэн
Li Zicheng held a grudge against Wu for his faithlessness, so he executed thirty-eight members of the Wu household, including Wu's father, whose head was displayed on the city wall. Enraged, Wu hardened his resolve to resist the new regime and defeated the Shun vanguard led by Tang Tong on 3 and 10 May. In June 1645, Wu Sangui captured Yulin and Yan'an. At the same time Li Zicheng was killed by a village head in Tongshan county, Hubei Province.
