Li Baochen (李寶臣) (718 – February 6, 781[1]), originally named Zhang Zhongzhi (張忠志), courtesy name Weifu (為輔), known as An Zhongzhi (安忠志) during the Anshi Rebellion and Zhang Baochen (張寶臣) 778–779, formally the Prince of Longxi (隴西王), was a general of the Chinese rebel state Yan, who later submitted to and became a general of the Tang dynasty, from which Yan had rebelled.
He was ethnically Xi and from Fanyang Circuit (范陽, headquartered in modern Beijing), but his original lineage was not otherwise known in history.
An Lushan rose against Emperor Xuanzong's rule in late 755, and Zhang Zhongzhi, hearing the news, escaped from Chang'an and joined An in Fanyang.
An Lushan subsequently put him in charge of defending the key pass of Tumen (土門, in modern Shijiazhuang, Hebei).
He, along with fellow Yan generals Xue Song, Tian Chengsi, and Li Huaixian, were allowed to keep their territory, and he was made the military governor of Chengde Circuit (成德, headquartered in modern Shijiazhuang, Hebei), consisting of six prefectures that he controlled.
Therefore, he began to systematically kill the stronger military officers in his army to eliminate potential challengers to Li Weiyue.
It was also said that in his old age, he became particularly superstitious and trusted sorcerers who predicted that he would have long life and supreme power (i.e., become emperor).
In 781, the sorcerers made him a potion that was supposed to yield long life, but instead was poisonous, and he died within three days of drinking it.
