 Instead, he ordered Zhao Dejun and Fan Yanguang (then the military governor of Tianxiong) to launch their troops to try to lift the siege on Jin'an.However, Zhao was intending to garner Khitan support for "him" to be made emperor instead, and therefore, as he approached Jin'an, stopped his army while engaging in secret negotiations with Emperor Taizong.Emperor Taizong was initially enticed (as he viewed Zhao's army to be still a strong one and difficult to deal with), but at the earnest beseeching of Shi's staff member Sang Weihan, decided to continue to support Shi.
