[1] It is not known when Li Huaixian was born, but it is known that he was from Liucheng (柳城, in modern Chaoyang, Liaoning) and that he was of Xiongnu stock.
Li Huaixian sent an army to pursue him, and Shi Chaoyi, believing the situation to be hopeless, committed suicide.
[3] After Li Huaixian's submission, the Tang imperial government was hesitant to move them, fearing another rebellion, and at the suggestion of the general Pugu Huai'en, Li Huaixian, along with fellow Yan generals Xue Song, Li Baochen, and Tian Chengsi, were allowed to keep their territory, and he was made the military governor (jiedushi) of Lulong Circuit (盧龍, headquartered in modern Beijing), consisting of six prefectures that he controlled.
The four former Yan generals formed alliances among themselves, as well as with two other military governors, Li Zhengji and Liang Chongyi, hoping to be able to pass their territories to their descendants, semi-independent of the Tang imperial government, retaining their armies and taxes without submitting them to the imperial government.
The Tang imperial government was subsequently forced to recognize Zhu Xicai as the new military governor.
