Chu army attacking Jingnan withdrew, but Li Jian still was able to capture Fu Prefecture. In 921, Gao ordered Ni, whose son Ni Zhijin () had married a daughter of Gao's by this point, to oversee a project to repair Jiangling's outer walls. When Gao himself went to review the project, he blamed Ni Kefu for the project's slow pace and publicly caned him. However, he stated to his daughter, "Go back to your home and tell your father-in-law: all I wanted to do was to display my authority in front of the people."
