The Self-Destruction of the Great Wall is used to describe the evil consequences of the king after killing his good subjects. This sentence is by no means an empty whim but has a source, and this allusion comes from the last sentence before his death after the killing of Tan Daoji in the Song Dynasty. The warriors rushed to the front line to defend the country to the death, he was invincible and never bowed his head, but in the end he was killed because of the suspicion of the emperor, and in the end he was exploited, and the emperor regretted it.
Huo Luguang was a famous general in Northern Qi, and his father was a great general. He grew up fighting with his father, and saw that his father ruled the army strictly and led by example. He vowed to be like his father. At the age of 17, he was honored by Emperor Shenwu as the governor. He is also known as a true archer. Because during a trespass he shot down a large bird with wings spread in the sky, and when the bird fell down, he found that it was a carving, so people praised this exquisite arrow technique.
Huo Luguang was very good to the warriors, and the warriors were willing to follow them to the death. After a successful battle, he and his warriors planned to return to the imperial court, but at this time the emperor ordered the disbandment of the army. However, he felt that the brothers who were born and died together had not yet been rewarded, so he decided to continue to lead the soldiers to the reward. A group of people returned to the capital in a mighty way to stand in front of the emperor.
This frightened the emperor, who thought that Hu Luguang was going to lead the soldiers to create his own rebellion, forcing him to give rewards to the soldiers, but this time the emperor began to be jealous of Huo Luguang in his heart. At this time, the imperial court was controlled by the villain Mutiba, and Huo Luguang hated them very much, and Mutiba also hated him very much.
Huo Luguang deeply understood the method of using soldiers to be invincible, almost all the famous generals of Northern Zhou were his defeated generals, and defeated him in the war with the famous general Wei Xiaokuan, who was unwilling to suffer huge losses. So I started to implement a counter-plan by a villain. He found someone to make up a song with the name of Huo Luguang. The gist was that Huo Luguang had long been preparing for a rebellion and had been raising troops to gather sharpness.
Of course, this song reached Mutiba's ears, and he was overjoyed to see this because he thought of a way to bring down Huo Luguang. In the song, he wrote another sentence about Huo Luguang's desire for dictatorship. He passed the song to the emperor's ear by means, and the emperor was already suspicious, and at this time he was murderous about such a song.
In 573 the emperor rewarded him with poisoned wine, and without such a general the country became no longer solid and powerful. After that, Northern Zhou destroyed Northern Qi. The Emperor of Northern Zhou said that if Huo Luguang had not been killed by you, how could I possibly destroy you Northern Qi?
By the time the emperor woke up, it was already too late, the country had perished, and he was no longer the emperor on top. It can be said that it is a self-inflicted evil consequence, which is also a self-destructive Great Wall.
