When Guan Yu persuaded Pang De to surrender, he mentioned his cousin Pang Rou but not his old master Ma Chao. This is because Pound has long since severed ties with Ma Chaoen. For Guan Yu, he had some understanding of the breakdown in the relationship between Ma Chao and Pang De. Therefore, when he persuaded him to surrender, he only mentioned Pang Rou, Pang De's cousin, and did not mention Ma Chao at all, in order to avoid irritating Pang De. However, even if Guan Yu uses Ma Chao to persuade Pang De to surrender, Pang De will not change his mind because he has long since severed ties with Ma Chaoen and there is no relationship between the two. It's useless to mention it.
In the end, facts also proved that Pound stood firm and would rather die than surrender. Guan Yu had no choice but to fulfill Pang De's loyalty and ordered him to be killed. This was something Guan Yu didn't expect. Guan Yu still wanted to persuade Pang De to surrender.
In the Romance of the Three Kingdoms, there are many wonderful stories. Among them is the story about the seven armies that were flooded. In it, Guan Yu persuaded Pang De to surrender, but Pang De would rather die than surrender. I admired him very much. You must know that both the generals Yu Jin and Pang De were captured alive by Guan Yu, and Yu Jin surrendered after being captured. If Pound had surrendered, not only would he not have died, but he might have developed well.
First of all, when Ma Chao was driven out of Guanzhong and fled to Hanzhong to join Zhang Lu, Pang De followed Ma Chao to Hanzhong. Secondly, when Ma Chao left Zhang Lu to join Liu Bei, Pang De did not follow, but stayed in Hanzhong and served under Zhang Lu. Zhang Lu was very angry at Ma Chao's betrayal, so he killed Ma Chao's son Ma Qiu. This shows that as early as the Hanzhong period, Pang De's relationship with Ma Chao broke down. Therefore, when Ma Chao betrayed Zhang Lu and joined Ma Chao, Pang De chose to break with Ma Chao. It is for this reason that Zhang Lu would also look at Pound in a different light, and not only spared Pound's life, but also made him his subordinate.
In my opinion, Pound is a loyal and righteous person, not a person who is greedy for life and afraid of death, and deserves the respect of future generations.
