Sun Chuanfang
Shangguan enrolled in the Infantry Division of Baoding Military Academy in 1917, and was the same class as Ye Ting and Gu Zhutong. After graduating in 1919, Shangguan served under the direct line of Sun Chuanfang, platoon leader for the guard, and was promoted all the way in Sun Army zhong. After the Beijing Coup in 1924, the Fengtian clique went south to occupy Jiangsu, and was soon expelled from the army by Sun. In 1925, with the support of Zhang Zongchang, Shi Congbin went south to attack Sun Chuanfang. Shangguan led a group of detours to the enemy, cut off Shi's retreat, and captured Shi Congbin in one fell swoop.
