1929 On May 20th, according to the policy of "developing outward and consolidating the Soviet area through development" jointly determined by the Military Military Commission and the Hunan-Jiangxi Special Committee, Peng and Teng led a total of more than 1000 troops from Jinggangshan and moved to eastern Hunan and northern Guangdong. The Red Fifth Army first captured Lingxian and Guidong in eastern Hunan and raised a batch of cash and materials. Later, he captured the city entrance of Renhua County in northern Guangdong, seized more than 200 guns and more than 30,000 bullets, and raised 30,000 yuan. Then through the Yangtze River and Fuxi in Renhua County, ready to capture Renhua County. Later, he learned that Nanxiong was not defended by the Kuomintang regular army, but only armed by local militia and guards, and its combat effectiveness was not strong. So I decided to attack Nanxiong instead and immediately headed for Nanxiong.

The Red Fifth Army passed Wenshao in Renhua, Baishun and Cangshi in Nanxiong and arrived in Nanxiong County on the afternoon of June 1. When Fang Xin, the county magistrate of Nanxiong of the Kuomintang, heard that the Red Army was coming, he panicked and hurriedly shaved and disguised himself. The vigilante and the guard also ran away. The Red Fifth Army successfully occupied Nanxiong City without fighting a battle. After learning that the Red Fifth Army had arrived in Nanxiong, Nanxiong County Committee of the Communist Party of China led guerrillas to attack vigilantes along Pinggang, Li Xi and Shuikou, and then went into town to meet the Red Fifth Army.

After the Red Fifth Army entered Nanxiong City, they lived in Wu Shang Temple (now Bayi Road Primary School) and Wu Xia Temple (now People's Hospital Outpatient Department). After check-in, we will carry out publicity work and hold a mass meeting in front of Wu Xia Temple, Confucian Temple (now Nanxiong Municipal Government) and Gospel Hall (now Nanxiong Traditional Chinese Medicine Hospital). Zhou Qunbiao, a member of Nanxiong County Committee of the Communist Party of China, presided over the meeting. Peng and Teng spoke at the meeting, focusing on publicizing the party's policies, the purpose of the Red Army and why the revolutionary cause won. Expose the crimes of Kuomintang reactionaries oppressing the masses and landlords and gentry exploiting poor peasants. Call on the broad masses to unite and overthrow imperialism! Down with Kuomintang reactionaries and landlords and gentry! Wu Gong's army is disciplined, committing crimes wherever it goes, and trading fairly, which is praised by the masses. Resolutely crack down on reactionary officials, local tyrants and evil gentry who have committed heinous crimes. According to the information provided by Nanxiong underground party and the demands of the masses, they suppressed Dong, executive member of the Kuomintang Nanxiong County Party Department and disciplinary member of the county police department, Liang, head of the county government, Zhong, a local tyrant and evil gentry, and so on. Burned down the Kuomintang Nanxiong county office; Confiscate the property of four firms that collude with reactionary officials to oppress the masses and distribute it to the poor; Prisons were also opened and a number of "political prisoners" and revolutionary masses were released.

Nanxiong underground party and guerrillas helped the Red Fifth Army to mobilize the masses, raise funds and shop in the county. The Red Fifth Army lived in Nanxiong for five days and raised more than 30,000 yuan. Because the local reactionary armed forces had already fled, only about 300 guns were seized. They used the money they raised to buy a lot of medicines, salt and cloth in Nanxiong, and also concentrated sewing workers in the whole city to make more than 1000 sets of gray cloth uniforms, which enriched the supply of troops.

On June 5, the Red Fifth Army left Nanxiong City and moved to Chongyi, Jiangxi Province. The Red Fifth Army came to Nanxiong to give specific guidance to the work and armed struggle of Nanxiong Party, promoted the development of Nanxiong revolutionary armed forces, cracked down on the reactionary rule of the Kuomintang reactionaries, increased the struggle confidence for the revolutionary people who were severely persecuted by the Kuomintang reactionaries after the failed uprising, and effectively promoted the establishment of Oil Mountain.
