僖宗已至兴元，令孜以谓天子播越，由己致之，惧且得罪，西川节度使陈敬瑄，令孜同母弟也，令孜因求为西川监军，杨复恭代为军容使。
After Emperor Xizong of Tang arrived at Xingyuanfu, Tian Lingzi believed that the emperor's exile was caused by himself. He was afraid of being convicted of a crime. Chen Jingguan, the governor of Xichuan, was Tian Lingzi's younger brother from the same mother. Tian Lingzi therefore requested to serve as the military supervisor of Xichuan, and Yang Fugong took over as the military officer.
