In 1934, the fifth anti-"encirclement and suppression" in the Central Soviet Area of Jiangxi failed.In order to preserve its strength, the Central Red Army was forced to conduct a strategic transfer.After arduous battles, the Red Army broke through the three lines of defense of the Kuomintang army and came to the Xiangjiang River.The enemy used natural dangers to increase their troops and set up a fourth line of defense, and the Red Army was in a dangerous situation.Li De, one of the three-person teams of the highest leadership core at that time, was a military adviser sent by the Communist International.He ignored the huge gap in strength between the enemy and us and insisted that the Red Army fight to the death.Without military power and leadership, Mao Zedong analyzed the current situation and proposed to avoid the real and make the weak, get rid of the enemy's main force, and go to Guizhou where the enemy's strength is weak, which was approved by most members of the Politburo.In January 1935, the Central Committee of the Communist Party of China held an enlarged meeting of the Politburo in Zunyi, Guizhou, ending the wrong line of "left" adventures within the party, elected Mao Zedong as a member of the Politburo, and established Mao Zedong, Zhu De and Zhou Enlai as the core of leadership.From then on, under Mao Zedong's correct judgment and command, the Red Army crossed the Chishui River four times, attacked the east and west, moved the enemy, and successfully passed through the Yi area and advanced northward.On the Long March, the Red Army forced the Dadu River, climbed snow-capped mountains, and crossed the grassland, overcame unimaginable difficulties.Many lesbians overcame personal emotions such as losing children, withstood the test like gay men, made great sacrifices for the revolution, and became heroines, such as He Zizhen, Deng Yingchao, Cai Chang, Wang Caixiu and others.Mao Zedong led the First Red Army to fight against Japan north and resisted Zhang Guotao's right-leaning escapist wrong line.After a long journey of 25,000 miles, the three main forces of the Red Army finally met successfully at Shanxi Castle, northern Shaanxi on October 10, 1936.Mao Zedong wrote at his desk: The Red Army is not afraid of the difficulties of expeditions, and thousands of rivers and mountains are just free.
