張作霖
Zhang Jinghui deserted Zhang Zuolin to join Wu Peifu's Zhili clique. He later rejoined Zhang Zuolin and served as his Minister of War in the Beiyang Government from May 1926 to June 1927 and as Minister of Enterprises from June 1927 to June 1928. Within a year he was appointed governor of the Harbin and China Eastern Railway Special District in northern Manchuria. However, following the death of Zhang Zuolin in the Huanggutun Incident on 4 June 1928, Zhang Jinghui’s relations with his son and successor, Zhang Xueliang, deteriorated. Nevertheless, both men participated in a national unity conference called by Kuomintang leader Chiang Kai-shek in January 1929 in Nanjing.
