He was then transferred to the outskirts of Changsha, where he held positions as the Chairman of the Hunan Provincial Farmers' Association and the Secretary of the Suburban District Committee, actively promoting the peasant movement.

However, facing overwhelming enemy strength, Jinggangshan eventually fell, and Peng led a breakout with heavy losses, leaving only 283 survivors from the Red Army units.

[6][4] The small remaining force successfully conducted a surprise attack on Yudu County, Jiangxi, but Teng was injured due to an accidental firearm discharge.

Teng was appointed Deputy General Political Commissar and subsequently took part in the First through Fourth Encirclement Campaigns in the Central Soviet Area.

However, by the end of 1933, Teng faced marginalization due to the influence of Wang Ming and Bo Gu and was forced to leave his position in the Third Red Army Corps, being reassigned as Director of the Armament Mobilization Department under the Central Military Commission.

In July 1934, Teng traveled to the Soviet Union to attend the 7th World Congress of the Comintern and studied at the Red Army Military Academy and the International Lenin School.

In August 1942, after the death of Zuo Quan, Teng became the Chief of Staff of the Eighth Route Army’s forward command and also took on the role of Director of the Intelligence Department.

[11] In 1944, Teng and Yang Lisan proposed the “Teng-Yang Scheme” to conserve resources and maintain logisticvs within Chinese communist military units.

[12] In August 1945, as Japan prepared to surrender, Teng led his troops in counteroffensive operations against the Japanese forces, successfully reclaiming vast amounts of lost territory.

[11][13] After the victory in the War of Resistance Against Japan, Teng Daiyuan was appointed Deputy Commander of the Jin-Ji-Lu-Yu (Shanxi-Hebei-Shandong-Henan) Military Region.

[14][15] In July 1946, to ensure that Liu Bocheng and Deng Xiaoping could lead the main forces to carry out key combat missions, Teng and Bo Yibo took charge of leadership responsibilities in the military region.

[21] In January 1965, Teng Daiyuan was elected Vice Chairman of the Fourth National Committee of the Chinese People's Political Consultative Conference.

Teng's memorial service was presided by then Vice Chairman of the Chinese Communist Party Ye Jianying and Deng Xiaoping delivered the eulogy.
