After the Revolution of 1911, he served in the North and South armies successively, and later under the command of Zhang. Shortly after the "Huanggutun" incident, he was incorporated into the National Revolutionary Army with the Northeast Army. 1929 The 48th Division was stationed in Hubei to participate in the Central Plains General Assembly War, and was promoted to 10 as the commander of the army due to the meritorious military service. 1in August, 930, Chiang Kai-shek established the Qing Xiang organization all over the country, and Zhou Yanhong was appointed as the "Qing Xiang" supervision office in the western border region of Hunan and Hubei, and was also the commander-in-chief of Hubei's "suppression of * * *" and led his subordinates to "surround" the Honghu base area of the * * * production party, suppressing the peasant uprising led by the * * * production party in Huang An and Macheng (historically,
From 1929, Zhou Yanhong's military career was once again transferred to his hometown of Hubei. In the next two or three years, Zhou Yanhong built a mansion in his hometown Cangbu. At the same time, on the side of the mansion, Cangxi Primary School was built on the former site of Cangbu Governor's Office, which was later changed to Jacky Middle School, which is the aforementioned Xinzhou No.2 Middle School. It was also during this period that Zhou Yanhong built a western-style neoclassical residence in Tanhualin, Wuchang, and settled here. During the war, Zhou Yanhong rushed back to Wuhan to reunite with his family.
1937, the battle of Nanjing started. In order to strengthen Tang Shengzhi's wartime determination to defend the capital to the death, Chiang Kai-shek dispatched a large number of troops to Tang's command. He thought that he could hold on for a while, stall the effective strength of the Japanese army and win the respite of the army. In exchange, the Nanjing government gradually withdrew to the west. Zhou Yanhong's department in Hubei was also sent to the East to take part in the war.
Zhou Yanhong's army was first sent to guard Qixia Mountain, and then to guard Wulong Mountain Scenic Resort. The Japanese attacked by sea and air force, and Zhou Yanhong led the army to resist, but failed to hold the fortress in the end. Within eight days, all the commanding heights outside Nanjing fell one after another, and finally Yuhuatai fell. The Japanese army stormed Nanjing from the commanding heights, and Nanjing failed to defend the war.
Zhou Yanhong and his troops were able to leave the battlefield and escape under the cover of hills outside the city. However, there are still100000 China soldiers in the city who can't break through and were brutally slaughtered by the Japanese army.
This fierce battle for life and death undoubtedly stimulated Zhou Yanhong's psychological state. Even though he was a soldier for half his life, in the next few years, he resolutely withdrew from the military and political circles, which cannot be said to have nothing to do with the experience of defending Nanjing in that year.
The Japanese army captured Nanjing and went all the way south to the Central Plains. 1in June, 938, the defense war in Wuhan began, and the peripheral war zones were selected in cities along the Yangtze River in Anhui and Jiangxi to stop the Japanese attack and force them to invade slowly. Li Zongren, Commander-in-Chief of the Fifth Theater, was hospitalized in Wuhan Nanhu Sanatorium because of a relapse of dental disease. Chiang Kai-shek appointed Bai Chongxi to lead the war. At that time, Zhou Yanhong, the 26th Army of the Fifth Theater, retreated to Huoshan and Lu 'an to block the enemy's advance after fierce fighting with the enemy in Hubei, Henan and Anhui. Yang Sen's troops stayed in Anqing and retreated after four days and nights of bloody battle because of the disparity in strength. Zhou Yanhong's troops left the Taihu Lake from Huoshan, cutting off the rear road of the Japanese army and causing heavy casualties to the enemy. The fifth war zone made the Yangsen Department and the Zhou Yanhong Department stick to it and prepare for a protracted war. Only in this way can we leave a slightly gentle space for Wuhan's "great retreat" to the southwest-the songs and dances before the fall of Wuhan were exchanged for the blood of the soldiers in front.
