The 31st Group Army traces its lineage to the Shantung Column of the Shantung Military Region which was formed around 1941. By 1945 the column had been reorganized and redesignated into several military districts, including the Chiao-Tung Military District. By 1946, elements of the Chiao-Tung MD were reorganized and redesignated 9th and 13th Columns. The 13th Column, commanded by Chou Chih-chien was composed of three divisions, including the 37th, 38th, and 39th. In the mid-to-late 1940s the 13th Column was reorganized and redesignated as the 31st Corps, also commanded by Chou Chih-chien. The 31st Corps was composed of the 91st, 92nd and 93rd Divisions.[4][page needed]
The corps became the core of the 31st Group Army.[8]

In early October 1991 the 258th Regiment of the 86th Motorized Infantry Division, along with units from various military sub-districts, conducted defensive exercises and combined militia exercises in the Banding Area, Lianjiang Xian, Fujian Province. In mid October to early November 1991 the 92nd and 93rd Infantry Divisions (since disbanded) of the 31st Group Army conducted routine training and field training activities in the Fuzhou area of Changpu and Nanan. In early April 1992 the signal corps of the 31st Signal Regiment conducted routine training and an overall signal training and evaluation between veterans and replacements in Xiamen, Fujian Province.[9]
