After the Chinese reunification at the end of the Northern Expedition, Tang was confirmed in his control of Rehe by the Kuomintang and made governor and commander of the 36th Division.
His many extortions and taxes gave him a great deal of revenue that he used to purchase luxury residences in the Italian concession in Tianjin.
With his capital soon to fall, Tang diverted 200 trucks assigned to support his army to transport his wealth to Tianjin.
On September 10, 1933, Tang met with Fang Zhenwu, Ji Hongchang and Liu Guitang, the remaining leaders of the Chahar People's Anti-Japanese Army at Yunzhou, where it was reorganized.
After the failure of Fang Zhenwu and Ji Hongchang's march on Peking, Tang turned on Liu Guitang and drove him out of Chahar in December 1933.
