In July 1941, the 2nd Army was ordered to expand into the 15th Army, governing the 2nd Army and the 92nd Army of Li Xianzhou. He Zhuguo was appointed Commander-in-Chief of the 15th Army. In the same year, Tang Enbo's 31st Army was transferred to Henan, Tang Enbo served as the deputy commander of the first theater, and the commander-in-chief of the four provinces of Jiangsu, Shandong, Henan and Anhui, and He Zhuguo served as the deputy commander of the four provinces of Sulu, Henan and Anhui. In fact, Tang Enbei was ordered by Chiang Kai-shek to monitor the Chinese Communist Party and the New Fourth Army. Because He Zhuguo had cooperated with the 120th Division of the Eighth Route Army in northern Shanxi and had frequent contacts with Yan'an, Tang Enbo was wary of He Zhu's state. The Kuomintang spy organization in Henan with Tang Bolai secretly investigated and monitored He Zhuguo, listing He Zhuguo's accusations of "accommodating the Communist Party", "communicating the enemy", and "smuggling", but it was lost because of no evidence.
