The History of the Three Kingdoms is quoted as saying: Pound Zi will unite Zhong and Deng to attack Shu and destroy Guan Jia.

After Si Mazhao destroyed Shu, all the people in Shu got preferential treatment, and the ministers of civil and military affairs were resurrected. Even Liu Chan was named the Duke of Happiness, but only the descendants of Guan Yu were not raised, but were extinct because Guan Yu killed Pound, the general of Cao Wei, when Fancheng flooded the Seventh Army.

From this point of view, Pound died on the battlefield, which was a fair death, but his son Pang Hui didn't think so. He was determined to avenge his father. When Pang Hui grew up, he challenged his father's title and embarked on the road of joining the army. In 263 AD, Zhuge Liang, the prime minister of Shu Han, had died in Wuzhangyuan. There were basically no generals in Shu except Jiang Wei, and Cao Wei was shelved by Sima's family.

Pang Hui, the son of Pound, followed Zhong Hui and Deng Ai to cut Shu. Liu Chan surrendered without a fight, and Pang Hui entered the city with Si Mazhao. Pang Hui cried and begged Si Mazhao. There is only one request, that is, to slay Guan Yu's descendants and avenge his father, so Guan Yu's family was killed.

As for the descendants of Guan Yu, there are two main arguments:

1. Guan Ping's son Guan Yue was taken away by his mother when Wu Jun attacked Jingzhou, so he survived.

According to the records of Jingzhou Prefecture and Jiangling County Records, Guan Ping married Zhao Yun's daughter and gave birth to a son named Guan Yue when he was guarding Jingzhou with Guan Yu.

When Wu attacked Jingzhou, Guan Ping's wife escaped from Jingzhou with Guan Yue, who was only eight years old. From then on, she changed her name and lived among the people. It was not until the Western Jin Dynasty wiped out Wu that she returned to Jingzhou City and restored the Guan family. Since then, she has lived in Jingzhou, taking guarding the tomb as her home. During the annual inspection of Yongzheng in the Qing Dynasty, Guan Yue was directly honoured by Dangyang Guanling, and during the Qianlong period, he was honoured by Jingzhou Guanmiao, giving a hereditary doctor of the Five Classics, and all miscellaneous schools were exempted.

2. Besides Guan Ping and Guan Xing, Guan Yu has a third son, Guan Suo, and these descendants are all descendants of Guan Suo.

There is no record of Guan Suo in the History of the Three Kingdoms. He is a folk legend in The Legend of the Crown Lock and The Popular Romance of the Three Kingdoms, which is not credible.

To sum up, whether Guan Yu's family was killed by Ponzi Club and whether Guan Yu's descendants stayed among the people is still a mystery and needs more evidence.
