 Erzhu Tianguang continued to control the western provinces, and in summer 531 he attacked the rebel general Suqin Mingda (宿勤明達) and captured him, taking Xia Province (夏州, roughly modern Yulin, Shanxi), which Suqin controlled, under his own control, while delivering Suqin to Luoyang to be executed.However, when the general Gao Huan rebelled at Xindu (信都, in modern Hengshui, Hebei) later in the summer, Erzhu Tianguang abandoned his planned campaigns against the rebel generals Gedouling Yili (紇豆陵伊利) and Moqi Shouluogan (万俟受洛干), who controlled the modern central and western Gansu, and prepared for possible action in the east, although he did not immediately intervene in the campaign between Gao and his fellow Erzhu clan members, even after Gao defeated Erzhu Zhao in battle late in 531.In 532, hoping to force Erzhu Tianguang to come to his clan members' aid so that they could be destroyed together, the generals Husi Chun and Heba Sheng (賀拔勝, Heba Yue's brother) persuaded Erzhu Shilong to put pressure on Erzhu Tianguang to act against Gao Huan.
