In 1932, the area from Chengdu to Neijiang in Sichuan Province was full of guns and guns. With Liu Xiang and Liu Wenhui as opponents, Deng Xihou, Liu Cunhou, Pan Wenhua, Tian Songyao, Yang Sen and other large and small warlords participated in the "Chengdu Battle".This is a melee between warlords fighting for territory.The melee of warlords brought heavy disasters to the people of Sichuan. Lavradin sent money and donations, collected food and taxes, smashed bones, murdered and set fires, and did everything. The poor people had nowhere to go.Just when the warlords were in full swing, a message suddenly pierced the night sky like lightning and shook Bashan Shushui like thunder: The Red Army is coming!

On December 18, 1932, the Red Fourth Front Army led by the Communist Party of China set off from the Hubei, Henan and Anhui base areas, marched thousands of miles west, crossed the Daba Mountains and entered Sichuan, and relieved the people.After the Fourth Red Army entered Sichuan, where the red flag was heading, all the people cheered, and the enemy was terrified.In just a few months, the Fourth Front Army of the Red Army smashed the "three-way siege" of the Sichuan warlord Tian Songyao, liberated Tong (Jiang), Nan (Jiang), and Ba (Central), mobilized the workers and peasants to establish a red base area; The three major battles of Ying (mountain) Qu (county) and Xuan (Han) Da (county) were devastated; the anti-"six-way siege" swept thousands of troops like a sweeping mat, and defeated the Sichuan warlords headed by Liu Xiang and fled.Thousands of impoverished people greeted the savior with pots of milk and food.

The Red Fourth Front Army mobilized the masses in the Sichuan-Shanxi Revolutionary Base Area, established party organizations and revolutionary regimes at all levels, and expanded the Red Army. In nearly a year, the base area expanded to more than 20 counties, and the Red Army grew to 80,000 people. The Sichuan-Shanxi Revolutionary Base Area became In the largest red revolutionary base area in Northwest China, the red flag of revolution is flying high in the mountains and rivers of Bashan and Shushui. In 1934, Mao Zedong said at the Second National Congress of the Chinese Soviets in Ruijin: "...due to the expedition of the Red Fourth Front Army, in the remote northwestern part of China, extensive mass revolutionary struggles were carried out, and the seeds of the Soviets were broadcast to the revolutionary situation. In less than a year, the Fourth Front Army of the Red Army has established Soviet power in more than 20 counties, and has grown its Red Army ranks by more than ten times, mobilizing workers and peasants in the entire Sichuan The masses and the White Army soldiers tended to the Soviet revolution, and established a new and powerful base for the Soviet revolution in Northwest China. The Sichuan-Shaanxi Soviet Area is the second largest area of ​​the Chinese Soviet Republic. The Sichuan-Shaanxi Soviet Area is a bridge for the development of the Soviet revolution between the north and south banks of the Yangtze River and the two parts of China. The Sichuan-Shanxi Soviet Area has a very huge role and significance in the great struggle for the new Soviet China.”

Although due to the development of the situation, in May 1935, the Red Fourth Front Army left the Sichuan-Shanxi Base Area and went northward with the Central Red Army, the Second Red Army and the Sixth Red Army Corps for the Long March. The military history and the history of China's revolutionary struggle have written a rich and colorful page, and the Bashan Red Flag will always fly in the hearts of the people of Sichuan and the whole country.
