Old Wang locked the door and stayed alone in the room. When it was time for dinner, he ignored his son's calling and did not open the door. His family thought something had happened to Old Wang, but they didn't dare to break down the door, only whispering among themselves in the courtyard.
Old Wang started pacing in the room again, his head filled with all sorts of chaotic thoughts. He found his family outside noisy, but that evening he did not lose his temper. After thinking for a long time, he walked to the door, opened it, and addressed his family, "Go about your business, I'm fine and not hungry, I don't want to eat anything."
Although the family did not understand what was going on with Old Wang today, seeing that he hadn't cursed at them and seemed to be alright, they actually did as Old Wang said and went about their business. Although they all found it very strange, they did not dare to interfere with Old Wang's matters.
