In March 1927, Deng arrived in Xi'an, northwest China from Moscow. He joined the army of Feng Yuxiang. Feng had asked the Soviet Union for help. But at that time, the Soviet Union supported the Communists' alliance with the Nationalists of the Kuomintang (KMT). In 1929 Deng led the Baise Uprising in Guangxi province against the Kuomintang (KMT) government. The uprising failed, and Deng went to the Central Soviet Area in Jiangxi province.
