At that time, a woman named xia was eating in the store. Tang Jun sent for her satchel and was caught by Fang Yonghong and others. Tang Jun took out a spring knife he carried with him and stabbed Chinese Yong Hong in the abdomen, then fled. Fang Yonghong died after being rescued, and was later recognized as a courageous person.
