Why did the stone statue kneel in front of Wei Yan's grave after Zhuge Liang died?

During the Three Kingdoms period in China at the end of the Eastern Han Dynasty, every country was struggling to unify the world. During this period, all kinds of fierce heroes rose in succession. At this time, many heroes took refuge in these three countries in order to survive in troubled times, and Wei Yan of Shu was such a person. Zhuge Liang is an important strategist in Shu, and plays an important role in Shu. Zhuge Liang had predicted that Wei Yan would rebel before his death, because he knew that Wei Yan would do a series of abnormal things after his death, so he arranged a series of things to limit Wei Yan before his death, but Zhuge Liang mistakenly thought of Wei Yan, but Wei Yan did it for the sake of Shu and planned to do it later. So when Wei Yan was there, there was a statue of Zhuge Liang kneeling beside his grave.

First, let's meet Wei Yan. Although Wei Yan had a high position in military command, he laid a lot of mountains and rivers for Shu, which won the trust of Zhuge Liang at that time. But as far as his character is concerned, he is indeed a sinister man. He won't reveal many things to others. He's just doing this in his mind. That's who he is. Zhuge Liang saw through him and knew that Wei Yan would definitely oppose Shu when he was around.

The second reason is that Zhuge Liang's own arbitrariness has caused such a reason. After all, he also knows that he will die in the near future. After all, Zhuge Liang is also a man who knows astronomy above and geography below, and has long known Wei Yan's plot. So he set up a series of tricks in front of the conference room to make people limit Wei Yan's actions.

The last reason is that Wei Yan did not win the trust of the military and civilians when he made the final decision. In this case, he has lost the trust of the people. So he will fail later, but after killing his stomach, they will understand why Wei Yan did it, just to make Shu more flat in the future development.
