Today, 90 years ago, on September 12th, 1935 (August 15th, 1935 in the lunar calendar), the meeting of the Political Bureau of the Central Committee opposed Zhang Guotao's split of the Central Committee. Telegram from the Central Committee of the Communist Party of China urging Zhang Guotao to go north. On September 12, 1935, after the Fourth Red Army entered Sichuan, it joined forces with local party organizations and local armed forces to establish the Sichuan-Shaanxi base area. The Fourth Red Army expanded into five armies with about 100,000 people. Under the command of Xu Xiangqian, it smashed the six-way "encirclement and suppression" of 200,000 enemy troops of Sichuan warlord Liu Xiang. Zhang Guotao was frightened by this fierce battle. On January 4, 1935, he called the Central Committee, trying his best to exaggerate the strength of the enemy around the Sichuan-Shaanxi base area and create an excuse for abandoning Sichuan-Shaanxi. In order to realize the intention of the First Red Army to cross the river from Luzhou to meet with the Fourth Red Army, the Central Committee instructed the Fourth Red Army to cooperate with the action and develop southwest with the main force. Zhang Guotao violated the orders of the central government and instead went northward to launch the Campaign of Southern Shaanxi, resulting in the deployment of defenses along the Sichuan-Guizhou border and the blockade of the Yangtze River. Under such circumstances, Zhang Guotao abandoned the Sichuan-Shaanxi base area without authorization and fled to western Sichuan under the pretext of cooperating with the Central Red Army going north. On May 18th, Zhang Guotao set up the "Northwest Special Zone Committee of the Communist Party of China" and the "Northwest Soviet Federal Government" in Maoxian County without authorization, and proclaimed himself the chairman. The Central Military Commission repeatedly instructed Zhang Guotao to go north, but he repeatedly opposed the correct strategic policy of the central government to go north to resist Japan and insisted on retreating to Sichuan and Kang. In order to solve the strategic policy, the central government held a meeting of Lianghekou and decided: "Concentrate the main force to attack northward." Zhang Guotao called the central government and threw out his retreat policy again. Zhang also instigated his cronies to ask for the reorganization of the Central Military Commission and the General Headquarters of the Red Army in the name of "Sichuan-Kang Provincial Party Committee", and proposed that Zhang Guotao be the "Chairman of the Central Military Commission". The Party Central Committee rejected this unreasonable request; Considering the current enemy, which is conducive to unity, Zhang Guotao was appointed as the general political commissar of the Red Army. Due to Zhang Guotao's obstruction, the Red Army stayed in Maogong and Maoergai areas for one and a half months. As a result, Hu Zongnan was able to control the traffic artery going north through Songpan with heavy troops, and the Red Army fell into a passive position. On August 4th, the CPC Central Committee held a meeting of the Political Bureau to discuss the current situation and tasks. At the meeting, Zhang Guotao was seriously criticized and educated, and the Resolution of the Central Committee on the Political Situation and Tasks after the Rendezvous of the First and Fourth Armies was adopted. In response to Zhang Guotao's warlordism, the meeting emphasized the party's absolute leadership role in the Red Army. After patient persuasion, education and serious struggle, Zhang Guotao ostensibly accepted the Party Central Committee's policy of going north to resist Japan. After the troops arrived in Aba area, Zhang Guotao's anti-party ambitions were greatly exposed, and he held his troops on the pretext that the Gequ River was rising. The armed forces that relied on their control refused to obey the central government's order to go north, stubbornly adhered to their retreat route, and actually pulled all the left troops back to Tianquan, Lushan and other areas. On September 12th, the Political Bureau of the CPC Central Committee held an enlarged meeting. At the meeting, Mao Zedong made a report on the Debate with Zhang Guotao and the Future Strategic Policy. The meeting unanimously agreed on the measures already taken by the central government and the strategic policy of continuing to advance northward in the future, opening up international ties through guerrilla warfare, and creating base areas in areas near the border of the Soviet Union in order to obtain assistance and then develop eastward. The meeting adopted Comrade Zhang Guotao's Wrong Decision. It is pointed out that it is wrong for Zhang Guotao to oppose the central government's strategic policy of going north and insist on the policy of retreating to the border between Sichuan, Kangzhou and Tibet. In order to implement his wrong policy, Zhang Guotao took the criminal act of splitting the Red Army, which is even more unallowable. In view of Zhang Guotao's anti-party crime of establishing a separate central committee, on January 22, 1936, the Political Bureau of the Central Committee ordered Zhang Guotao to immediately abolish the puppet central committee, abandon his anti-party position, stop all anti-party activities, and decided to announce the decision of the meeting within the party. Zhang Guotao's behavior of splitting the Party and the Red Army was resolutely opposed by Zhu De, Liu Bocheng and others. Zhang Guotao besieged Zhu De and threatened him to issue a declaration against Mao Zedong and going north to resist Japan. Zhu De sternly refused and insisted that the whole party had only one Party Central Committee led by Mao Zedong. In extremely difficult circumstances, safeguard the unified leadership of the CPC Central Committee and Mao Zedong. Later, Zhang Guotao publicly expressed his suspicion of the Communist Party, was desperate for the future of the revolution, and openly voted for the Kuomintang spy group. On April 18, 1938, the CPC Central Committee decided to expel Zhang Guotao from the party, which won the support of the whole party.
