Liu Bingyi is the grandson of the criminal prince, who is the son of Wei Zifu. Later, due to witchcraft, Liu Bingyi was spared the death penalty because he was young.
By the way, the first queen of Liu Bingyi was Xu Pingjun, but later she was killed by Huo Guang's daughter. Huo Guang's daughter is the second queen of Liu Bingyi, named Huo Chengjun.
Huo Guang is Huo Qubing's half-brother (who once played Da Mo ballad), and Yun Ge is uncle and nephew. Yu Meng should be the adopted son of Master Jiu.
As for the Shangguan family, it is not clear. May be the descendants of Shangguan Jie, Shangguan Jie, Jin Ridi (hee hee, can't play), Huo Guang and Sang Hongyang. The other is the Shangguan Queen, the Queen of Liu Fuling, and Huo Guang's niece.
