In January 1924, at the First National Congress of the Kuomintang held in Guangdong, Fan Zhongxiu was elected as an alternate supervisor of the Central Committee. In September, wars broke out in Jiangsu and Zhejiang. On the one hand, Sun Yat-sen ordered Xu Chongzhi and others to lead the Guangdong and Yunnan armies to eliminate the rebellious forces of Dongjiang and ; on the other hand, he ordered Tan Yankai and Zhang to lead the troops of Hunan and Henan to go to the North Expedition of Jiangxi, and appointed Tan Yankai as the commander-in-chief of the Northern Expedition Army. Then he ordered the Northern Expedition Army to be renamed the "Kinship Army", and at the same time ordered Fan Zhongxi to be the "Chief of the People's Army". In November, Tan Yankai was attacked by Fang Benren and Chen Jiongming in Ganzhou , and had no choice but to return to Guangzhou.
In this way, Fan Zhongxiu was unable to support his troops in the Jiangxi battlefield, and the troops suffered heavy casualties. So on November 21, 1924, he led his troops to move along the border of Hunan and Jiangxi, and passed through Ninggang, Lotus , Liling , Liuyang , Pingjiang, Xianning , and arrived at the Wuxue Ferry. Since the Northern Expedition in mid-September, Fan Zhongxiu has led his troops to march for more than 80 days, fought more than 50 times during this period, traveled to 4 provinces, with a total journey of more than 5,000 miles. Because Sun Yat-sen ordered Xiong Jinhuai, a revolutionary from northern Hunan, to do the work of connecting Xiao Bingnan, Fan Zhong Xiucai was able to cross the Yangtze River and arrived at Huangchuan through Luotian .
As soon as he arrived in Henan, Fan Zhongxiu received a telegram from Sun Yat-sen from Beijing, saying that Wu Peifu hiding on Jigongshan , and ordered Fan Zhongxiu to "annihilate this canal leader" to avoid leaving any disaster. But Wu Peifu had already left Jigong Mountain and ran south again.
After Fan Zhongxiu returned to Henan, the founding and Henan Army named after Sun Yat-sen was called on, and local teams and green forest heroes came to join him one after another. In just a few months, the troops reached 30,000 to 40,000. Hu Jingyi, who was then the deputy commander-in-chief of the National Army and the commander of the Second Army, supervised Henan. He warmly welcomed Fan Zhongxiu's return to his hometown in Henan, and also specially designated the counties in southwestern Henan as Fan Zhongxiu's garrison.
From February to March 1925, Liu Zhenhua, the leader of the Song Army in Shaanxi, instructed his most powerful Han Yukun and Hu Jingyi to compete for Henan. So Hu Jingyi led his troops to fight Han Yukun in the Gongxian and Yanshi areas. Fan Zhongxiu led his troops from Yuxian and Dengfeng to the south bank of Luoshui to assist the Second National Army in attacking Han Yukun sideways. During the Hu Han battle, Fan Zhongxiu captured more than 10,000 Han Yukun's troops, seized dozens of local cannons, tens of thousands of guns and more than 1 million bullets, and his strength improved by leaps and bounds. After Han Yukun's defeat, Fan Zhongxiu led his troops to Luoyang . After the end of the "Battle of Hu Han", Hu Jingyi died of illness inexplicably. In this way, Yue Weijun took over as the commander of the Second National Army and also supervised Henan. So Yue Weijun recruited miscellaneous troops in Henan, but the only exception was the Jianguo Henan Army. Fan Zhongxiu often said: "The founding of the Henan Army was appointed by Marshal Sun. Who dares to change my flag!"
Happy entertainment enthusiast: Since then, Fan Zhongxiu has become a firm follower of Sun Yat-sen! He was loyal and devoted to following Sun Yat-sen, trying every means to expand his troops and fight to clear away all warlords who opposed Sun Yat-sen!
