Because Mu Liankui and others were to be released, as the son, younger brother, and uncle, Mu Zhongqing should go to the prison to receive them. Cai Wei was afraid they would take advantage of her absence to bully her father or make unreasonable demands. Hence, she also intended to go. However, Mu Zhongqing stubbornly refused, not allowing Cai Wei to accompany him under any circumstances.
The reason Mu Zhongqing refused his daughter was simple. Because Cai Wei had turned in three generations of Mu Liankui's family, the old man must have harbored deep resentment. If the old man saw her now, he would most definitely fly into a rage! He knew his daughter could handle herself, but he couldn't accept the sight of her fighting with her father in the street.
