Old mu was an old fogey. The MU family's culture was very strict. The children of the MU family, Mu Chen, mu Liang, mu Yuan, and Liu Zheng, were considered upright. Even if they had some small flaws in their characters, none of them were evil. Liu Zheng, Mu Chen, and mu Yuan were righteous and loyal. They were the five good men of the new era.
Elder mu had been upright and outspoken all his life. After giving birth to the old mu brothers, he was also brought up very well. A family like theirs had their own heritage and unique family culture. Old mu had spent many years and still had not accepted mu Yuan's unconventional love.
