Who did Wei Guan's daughter (who almost became an idiot emperor Sima Zhong) marry?

Wei Shuo: Zi Maoyi, a calligrapher in the Western Jin Dynasty. Hedong Anyi (now Xia County, Shanxi Province) was born, and she was the daughter of a health official. The calligraphy of Wang Xizhi and Wang Xianzhi is highly praised by the world, but who do they learn from? But few people pay attention to it and few people know it. Incredibly, the teacher of Wang and his son turned out to be a woman who left home to defend herself. This little-known talented woman is called Wei Shuo, and later generations are respectfully called Mrs. Wei. She is the daughter of Wei Guan, one of the famous families in the Eastern Jin Dynasty. Wei Guan was not only good at martial arts at that time, but also good at cursive writing. Mrs. Wei's family background is profound, and official books are outstanding. Once had the reputation of "the ice in the jade pot, the moon in the rotten Yao platform, the graceful tree, and the cool wind in Xu Lai". The book "Book End" also specially praised her sentence: "Mrs. Wei's official script is especially good at composition." With such a good teacher, it is no wonder that Wang and his son write so well.
