May I ask Xue Rengui, Xue Pinggui, Xue Gang, Xue Song what is their relationship ah, is it a family?

Xue Pinggui and Xue Rengui are one person, right? Wild history has confused the two. The biographies of the two men are very similar.

The commentary goes like this:

Xue Rengui is the grandfather, Xue Dingshan is the son, Xue Gang is the grandson, and Xue Kwai is the great-grandson. It's not too clear who Xue Song is.

Xue Song, grandson of Xue Rengui. He was a bold man, famous for his arm strength in riding and shooting. Later, he joined An Lushan's rebel army and was rewarded for his achievements in battles,

and was made Yecheng county governor. After Shi Chaoyi defeat, Xue Song to phase, Wei, lluvia, Xing four states surrendered to the Tang, was appointed Zhaoyi Festival Minister. In the reconstruction work after the chaos, Xue Song made a great contribution, so that Zhaoyi town quickly restored life. Xue Song is good at cuju, and was advised by a hermit, so he stopped, and picture its shape on the right side of the seat, to remind himself (is this the origin of the motto ah). The Tang Dynasty Emperor Yongtai eight years (773 years) died of illness.

Xue Rengui great-grandson is Xue Kwaidu, records do not have much.
