Yang Feng
In 195, when internal conflict broke out between Li Jue and Guo Si in Chang'an, Zhang Ji succeeded in mediating the conflict and persuading both sides to make peace. Zhang Ji also suggested letting Emperor Xian leave Chang'an and return to the old imperial capital, Luoyang. Emperor Xian then promoted Zhang Ji to General of Agile Cavalry (). However, Zhang Ji later had disagreements with the generals Yang Feng and Dong Cheng, who were escorting Emperor Xian back to Luoyang, so he allied with Li Jue and Guo Si to attack Yang Feng and Dong Cheng in an attempt to capture Emperor Xian and bring him back to Chang'an. However, the emperor had already escaped and taken shelter under the warlord Zhang Yang.
