第4野戦軍
After the Chinese Civil War resumed between the Communists and Kuomintang in 1945, Qiu served in Manchuria as political commissar of the Eighth Column of Lin Biao's Fourth Field Army. Qiu, being a relatively junior officer, was not particularly close to Lin Biao at the time. He did not meet Lin in person until 1948, when Lin put him in charge of logistics of the Fourth Field Army. Qiu did work closely with Huang Yongsheng, who was commander of the Eighth Column. They participated in the Liaoshen Campaign, Pingjin Campaign, and the Hengbao Campaign.
