Shu was destroyed, why was Guan Yu's descendants destroyed and Zhang Fei promoted to rank instead?

In 263 A.D., three roads cut Shu, Jiang Wei retreated to Jiange, confronted Zhong Hui, Wargo sneaked into level tone, and Zhuge Zhan was defeated. Wu couldn't save him and perished. Said surrender, sealing happy male; Zhang Fei's second son, named Liehou; Guan Yu was killed. Liu, who became sworn in Taoyuan, why did Guan Yu's family end up miserable?

Why was Guan Yu exterminated?

Guan Yu's genocide is not recorded in Chen Shou's "History of the Three Kingdoms", but Pei Songzhi quoted "Ji Shu", and only one sentence was attached to Guan Yu's biography: Pound, Tong Zhong, Deng, attacked Shu, Shu was destroyed, and Guan Jia was destroyed.

The culprit of genocide is Pound's son? Pang Hui, the cause of genocide can be traced back to the grievances of the previous generation. Guan Yu flooded the Seventh Army, and Pound was defeated and captured. At that time, Pound's brother Pang Rou was appointed as the general under Liu Bei's account, so Guan Yu persuaded Pound to submit to Liu Bei, and Pound would rather die than surrender, but cursed Liu Bei instead? Big Ear Thief? . Guan Yu was so angry that he killed Pound. Later, when Zhong Ai split his troops to attack Shu, he led an army to attack Shu, wiped out Guan Yu's family and avenged his father.

Why did Zhang Fei's descendants become officials and knights instead?

After Zhong Hui destroyed Shu, Zhang Fei's family was saved. First, the second son Zhang Shao made contributions to the city, and Wargo killed Zhuge Zhan in Mianzhu. Liu Chan sent Qiao Zhou, a doctor of Guanglu who was serving at that time, and Liang Fenglai, a surname, to surrender to Wargo. Of course, the most important thing is Zhang Fei's contacts.

Zhang Fei's wife is the cousin of General Wei, not Xia's second son, so Zhang Fei's wife is Xia's niece. The History of the Three Kingdoms quotes Wei Lue. When Jian 'an was five years old, Shiba was a 13-year-old sister. In this county, he went around collecting firewood for Zhang Fei. Knowing her good daughter, the concubine married her, gave birth to a daughter and became the queen of Liu Chan. Therefore, when Yuan died, Fei's wife invited him to be buried. ? It is said that in AD 200, Xia Houba's thirteen or fourteen-year-old cousin went out to pick up branches and mow the grass. Zhang Fei took a fancy to him, married him home, and gave birth to a daughter for Zhang Fei. Zhang Fei also married Liu Chan and became a queen. At that time, although the Xiahou family was no longer the glory of the year, it was at least once a Cao Wei Xun Gui. No matter from Shu or Wei, be kind to Zhang Fei's family.

Of course, Ji Shu is the only one who recorded Guan Yu's extinction, but Chen Shou, who is closest to the times, did not record this event, so its authenticity still needs to be examined. Therefore, as for whether it is true or not, everyone has different opinions.
