After the Yan Army entered the city, Second Prince Murong Ping followed Murong Yan's instructions, ordering the Yan Army not to burn, kill, or loot from the civilians, and announced Yan's new political policies in Chang City.
The civilians knelt and thanked the emperor's grace, while the Wei nobles who remained in Chang City were filled with resentment, unwilling to leave the old capital of Wei. They intended to negotiate with Murong Ping, planning to use the support of their Wei old aristocratic family to coerce Murong Ping, but they didn't even get to see Murong Ping's face.
The implementation of new policies would harm the interests of the old aristocracy. At that time, it was precisely for this reason that the Yan Kingdom, after Empress Ji's reforms, was scorned by the noble families of various states.
