To exploit this success the high command committed the balance of the 31st Army Group, from the Northern Hupei Army. Its main force was ordered to launch an attack from the Gaocheng, Yanzihe area and attack the area of Huayuan and Guangshui by January 1, 1940. On the 5th it attacked Japanese units at Haodian, Yu-chia-tien [Wujiadian?], Mount Hua, Ta-miao-fan and Pingchangguan. Later, the 23rd Division (85th Corps?) advanced to the area between Wu-sheng-kuan [Wu-sheng pass?] and Guangshui. On January 7, 4th Division (85th Corps?) recovered Mount Hua. On January 17, the 4th, 21st and 141st Divisions engaged the Japanese at Wujiadian, Chien-ting-miao, Lo-han-ting, and Mount Hua.
