And what was Mu Qiuniang busy with during this time?
It turns out that recently Mu Bai suddenly asked her for a favor—to discipline her troublemaking brother Murong. Mu Bai was not an only child; she had a younger brother two years her junior named Murong, who was even more unruly than her, causing headaches for everyone.
Her rebellion at most involved wanting to make films, having a bad temper, and offending some people, but this Murong purely belonged to the sort who looked for trouble when there wasn't any. If he disliked someone, it probably wasn't for any special reason; maybe he just thought they were more handsome than him, which made him uncomfortable and he wanted to teach them a lesson.
This time, Murong ran into a hard wall. He snatched a woman from Yan Hao, one of the "Capital City Four Young Masters," and was severely beaten up, ending up with a head injury and spending a month in the hospital.
