Liu Zongkuan was the heart and belly of the famous anti-Japanese general Yang Hucheng, and Liu Zongkuan was introduced by Yang Hucheng, Liu Zongkuan, who studied at Northwest University in his early years, graduated from the third phase of the Whampoa Military Academy and the second phase of the Army University. After 1926, he served as the colonel's chief of staff, regimental commander, and deputy brigade commander of the major general in the Yang Hucheng Department of the Northwest Army. After 1937, he successively served as senior staff officer of the Kuomintang 38th Army, chief of staff of the Shaanxi Provincial Military District, chief of staff of the Seventh Branch of the Central Military Academy, commander of the provisional 15th Division, and deputy director of the General Officer Class of the Army University. In 1943, he joined the Chinese National Liberation Action Committee.
In the Xi'an accident, Yang Hucheng was tragically poisoned, Liu Zongkuan was also imprisoned, and after his release from prison, Sun Weiru, chairman of Shaanxi Province, arranged that Liu Zongkuan successively served as a senior adviser to the major general of the 38th Army Headquarters. Then, because of Hu Zongnan's slander, he was almost shot by Chiang Kai-shek, and finally Feng Yuxiang came forward and was sentenced to 13 years in prison! He was released on bail not long after spending time in prison.
In October 1945, after the victory of the Anti-Japanese War, the Kuomintang government returned to Nanjing, and established the Chongqing Xingying (the predecessor of the Southwest Governor's Office) in Chongqing, with Zhang Qun as the director. Zhang commissioned Xu Peigen, the chief of education at the Army University, to find a chief of staff in charge of the military. After discussing with Zhang Pei, Xu Peigen recommended Liu Zongkuan to go. At that time, Liu Zongkuan was no longer willing to serve Chiang Kai-shek and was secretly planning to go to Yan'an. He was unwilling to help Chiang Kai-shek fight the civil war, nor did he want to implicate the guarantor by going to Yan'an. Liu Zongkuan found Guo Zeshen and told him his thoughts and asked him to make up his own mind. Guo Zeshen listened and immediately realized that this matter was not trivial, and he did not immediately express his position, but quickly reported it to the CPC side.
Liu Zongkuan's troops belonging to Chiang Kai-shek at this time, coupled with the fact that Old Chiang attached great importance to this defense, summoned several generals of the Concubine Clan to discuss in detail after the meeting, including Liu Zongkuan, and several others seemed very impatient, and Liu Zongkuan kept staring at Old Chiang Kai-shek while pointing to the map and explaining, recording all the details, and the meeting was over.
After the meeting, Liu Zongkuan listed a long letter of intelligence on the map, as well as the defense system of the Kuomintang in the southwest region, the location of the troops, and the meticulous situation, and handed it over to the comrades of the Open Party, which was constantly handed over to the central authorities and handed over to the commanders of the major field armies, and later played a serious role in the liberation of the southwest.
After Liu Zongkuan's last piece of information was sent, Liu Bocheng ordered his troops to rush in day and night, and as a result, Zou Fengchun, who had set up a secret radio station in Chongqing, entered Chongqing at the same time as the vanguard of the People's Liberation Army who marched into Chongqing. After Zou Fengchun entered the city, according to the original agreed contact location, he quickly got in touch with Fang Xianzhi. On the evening of December 2, Fang Xianzhi and Zou Fengchun, together, took a jeep from the Southwest Military Region of the Chinese People's Liberation Army to Shapingba to take Liu Zongkuan back to the city and arranged for Liu Zongkuan's family to live in the Lianglukou Special Garden. According to Zou Fengchun, the original marching plan hoped to reach Chongqing before the Spring Festival, but it was liberated on November 30, a full two months ahead of the original march plan.
