As we all know, Gao Yang is the second son of Gao Huan, the Divine Emperor of Northern Qi, and is a relatively special person. At a young age, he occasionally showed some signs of genius, but as he grew older, he became more and more obtuse. The nose is often hung on the nose, which gives people the impression of a slug.

In daily life, Gao Yang is regarded by everyone as a poor incompetent, for a simple reason: Do you think that a person who has passed the age of 15 and still has a runny nose all day will have a high IQ level? In ancient times, some men reached this age and not only had their own children, but even achieved great success in the military and political fields.
When Gao Yang was very young, his father did not believe that his son would become more and more stupid. Once, in order to test his son, his father Gao Huan took out some silk balls and asked him to unravel them. When the other brothers began to dismantle it in sweat, Gao Yang took out a waist knife, cut the silk ball into several pieces, and said: "Where the chaos is, it will be cut!" After that, his father looked at him with admiration.
Another time, Gao Huan asked the soldiers to disguise themselves as thieves and attack their young sons to see how they coped with an emergency. The eldest son, Gao Cheng, was so frightened that he wet his pants, while the second son, Gao Yang, violently pulled out a knife and slashed at the "robber". It wasn't until all the "robbers" surrendered that Gao Yang gave up. Since then, Gao Yang's IQ seems to have shown a downward trend with age.
The older he gets, the more he tends to be silent, and according to historical analysis, it is likely that Gao Yang is pretending to be stupid. Because Gao Cheng was afraid that potential competitors would pose a threat to his position, Gao Yang had been worried about his own life. Moreover, after the death of his father Gao Huan, Gao Yang became more and more worried that his brother would murder him. Later, in order to hide his eyes and ears, pretending to be stupid became a way of self-protection adopted by Gao Yang.
As we all know, Gao Cheng has always been domineering and lustful, even his brother's wife. Although Gao Cheng married a princess of the Yuan Wei royal family, he was with Gao Yang's wife every time. Because Gao Yang's wife, Li Zu'e, was born noble, not only knowledgeable and courteous, but also a world-class beauty. Therefore, Gao Cheng felt very wronged, and the good cabbages all let the pigs arch, and such an idiot married such a beautiful woman as his wife.
As a result, Gao Cheng often bullied his brother. However, even so, Gao Yang remained silent, allowing Gao Cheng to possess his beautiful wife. At the same time, Gao Cheng also said sarcastically: "If this fool can become a great instrument, wouldn't the people under that day be talents?" ”
In that year, the eldest brother Gao Cheng did his best to defeat the rebellious Hou Jing, and gradually recovered all the territory that Hou Jing had sold to the enemy. After that, his prestige was unprecedentedly high, so that Gao Cheng was more likely to ascend to the throne. However, at the most proud moment of his life, he was stabbed to death by an insulted slave because of his own arbitrariness. That year, Gao Yang had just turned 18 years old.
After the crisis, 18-year-old Gao Yang suddenly wiped his nose and became a god man overnight. At that time, the oppressed Emperor Xiaojing, after hearing the news of Gao Cheng's death, shouted: "My hard life is coming to an end!" But who would have thought that in the next period of time, after seeing Gao Yang's performance that was once mentally retarded, Emperor Xiaojing's cheers turned into lamentations: "The former wolf has just left, and the rear tiger has come again, I don't know when I will die!" ”
Then, Gao Yang immediately rushed back to the Gao family's old nest and took over the power of the soldiers and horses. When Gao Yang came to Emperor Xiaojing's palace with a group of people and horses, the poor puppet emperor saw that the previous Gao Yang had completely changed, a cold face, full of forced heroism.
In addition, with him came eight thousand swordsmen, all of whom seemed to be heavily trained and loyal to Gao Yang. Among them, more than two hundred people walked up the steps of the palace with Gao Yang, and each of them rolled up their sleeves to reveal the blades in their hands, showing the appearance of facing a strong enemy. Emperor Xiaojing was almost frightened and stupid, staying where he was and not knowing how to be good.
In fact, Gao Yang was not optimistic before, and even his mother Lou Zhaojun angrily scolded: "Your father is like a dragon, your brother is like a tiger, they don't dare to usurp the throne, what else do you dare to do?" But in the end, the emperor's throne was "abdicated" from the puppet emperor to Gao Yang's body. From the time his eldest brother took power to forcing the puppet emperor to abdicate, Gao Yang spent only eight or nine months doing things without dragging mud and water, and finally, he created the Northern Qi Dynasty.
In the blink of an eye, the 20-year-old Gao Yang became the founding emperor of the new dynasty. Emperor Xiaojing, who had lost the throne, lived a miserable life, and a year later, the foundation of the Northern Qi regime was already quite strong, and Emperor Xiaojing became a useless burden. Finally, on the tenth day of the first month of December in the second year of Tianbao, when Gao Yang set up a banquet to entertain Emperor Xiaojing, he secretly poisoned the cup, and Emperor Xiaojing died of poisoning without defense. Subsequently, his three sons were also killed by Gao Yang.
However, there is no direct evidence in the history books that Gao Cheng's death is half related to Gao Yang, but Gao Yang's performance before and after is very different, and it is difficult to believe that he really has nothing to do with this matter. As a result, this "conspiracy theory" gradually spread, and more and more people believed that it was Gao Yang who planned the whole incident, killed his eldest brother Gao Cheng, and finally, took over all this.
In addition, when Gao Yang handled this matter, he personally killed the murderer. If this is a plot, then the only evidence has been destroyed by Gao Yang. But in any case, Gao Yang at least seized the opportunity of the times to usurp the throne successfully, and in the turbulent era of the Southern and Northern Dynasties, founded the Northern Qi Dynasty. In the end, Gao Yang lost his body due to drinking alcohol and died violently at the age of 34 on october 10, 10th year of Tianbao.
