Meng Tian said these two words before his death: "From my ancestors and descendants, I have accumulated trust in Qin Sanshi; Today I will send more than 300 thousand troops, which is enough to betray. However, those who know how to die and defend their righteousness dare not humiliate their ancestors and forget their teachings. "That is to say, since Meng Tian's grandfather, three generations of Mongols are highly valued by the king of Qin, while Meng Tian, though armed to the teeth, never thought of rebellion. Even in this case, Meng Tian can stick to his morality and not rebel, because he wants to live. Meng Tian didn't do this because he didn't want to live up to the teachings of his ancestors and the kindness of the emperor.
Meng Tian's words expressed Meng Tian's loyalty as a courtier and the spirit of sacrificing his life for justice, so Cao Cao was deeply moved by Meng Tian's two words. Because the situation of Cao Cao is similar to that of Meng Tian, Cao Cao's generation is the fourth generation. Moreover, when Cao Cao was 56 years old, he summed up most of his life and said that he didn't want to replace the Han Dynasty and set up his own home, indicating that he was loyal to the Han Dynasty.
When Cao Cao read these two sentences of Meng Tian, he was "not afraid of tears." He himself explained the reason in the Story: "An orphan, a father, and even a lonely person should be the responsibility of parents. It can be said that a believer and a son, Brother Huan, are also three generations." Therefore, for Cao Cao, he hopes that his loyal minister in the Han Dynasty can be recognized, which is also reflected in the narrative order, which reads: "It is also his ambition to seal the Hou as a general to levy the West, and then build a tomb, saying' the tomb of Cao Hou, the general to levy the West in the Han Dynasty'."
