Why was Guo Ziyi's ancestral grave dug after his death?

Guo Ziyi made great contributions to the establishment of the Tang Dynasty, and his achievements were outstanding at that time. But why was Guo Ziyi's ancestral grave dug? In fact, Guo Ziyi's ancestral grave was dug because Guo Ziyi's meritorious service was outstanding, which made Yu Chaoen, the eunuch at that time, very dissatisfied, so there was the event that Guo Ziyi's ancestral grave was dug.

First, the reason why Guo Ziyi's ancestral grave was dug After the Anshi Rebellion broke out, Emperor Xuanzong of the Tang Dynasty fled to Shu, and then Hengli began to proclaim himself emperor. Since then, Yu Chaoen has been appreciated by Hengli. However, in the same period, Guo Ziyi made great contributions to the Anshi Rebellion and was also reused by Hengli. This caused Yu Chaoen's dissatisfaction with Guo Ziyi. Therefore, Yu Chaoen embarked on the road to defeat Guo Ziyi. Yu Chaoen framed Guo Ziyi many times, but every time Guo Ziyi escaped. Yu Chaoen was so angry that he sent someone to secretly dig the ancestral grave of Guo Ziyi's family.

Second, Yu Chaoen Yu Chaoen was originally the supervisor of Li Guangjin's army. Later, he was appointed as a formal prosecutor by Hengli. Yu Chaoen's position often serves in the army, so Yu Chaoen must have military service if he wants to be promoted. But in front of Hengli, it was Guo Ziyi's numerous military achievements that stole his thunder. Therefore, Yu Chaoen hates Guo Ziyi very much.

Third, Guo Ziyi and Guo Ziyi first helped Tang Jun pacify Hequ, and then helped Hengli recover Hedong, Hexi and Henan. Therefore, Guo Ziyi's achievements in the army are unparalleled. Because of this, Hengli also attaches great importance to Guo Ziyi. But later, the imperial court wanted to send you to attack Hebei. At that time, Tang Suzong asked Yu Chaoen to be the commander-in-chief of that battle. So Yu Chaoen began to seek personal gain from the public and took the opportunity to retaliate against Guo Ziyi and others. In the face of their suggestions, he resolutely denied them, which eventually led to the collapse of 600,000 imperial troops due to chaotic deployment.
