Zhuge Liang actually offended many people in front of him, especially Sima Yi, and hated him so much that he could not defeat Zhuge Liang before his death, so he must take it out after his death. At that time, Zhuge Liang was afraid that this would happen, so he didn't want people to know where he was buried, so he designed this legacy. After his death, basically no one can find his grave, so he is not afraid of retaliation after his death.
Really? The coffin was lifted south, and the rope was broken and buried? Zhuge Liang didn't say it casually, but predicted it before he died. He predicted that there would be an earthquake in the south, so if two people carried his coffin to the south, as long as there was vibration, the rope would break. Moreover, he told the two men carrying the coffin to keep walking, not stopping, just in time for the earthquake. Moreover, after the earthquake and mountain collapse, his coffin will be buried in situ.
Of course, Zhuge Liang didn't actually tell the two men who carried the coffin. After all, these two men must have died in the mountains, which is also Zhuge Liang's selfishness. In fact, he has figured it out. As long as two people carry the coffin and then wait for the mountain to collapse, these two people will be buried with their own coffin, so no one in the world knows where Zhuge Liang's coffin is buried. So even those who want to get back at Zhuge Liang can't find a position.
Although Zhuge Liang has been clever all his life, he is also afraid that he will not get peace after his death, so he will arrange his coffin burial method in advance. Even if he is dying, he will arrange his coffin properly, which shows that Zhuge Liang is very calculating.
