The Southern and Northern Dynasties period was another era of great division after the Three Kingdoms, and the Northern Wei split into the Western Wei and Eastern Wei after a series of upheavals, but both regimes were in the hands of their respective vassals. The Eastern Wei chancellor Gao Huan firmly controlled the imperial government, and after Gao Huan's death, the eldest son, Qiu Cheng, succeeded him, who strengthened Gao's power internally and prepared to stand on wei's behalf, but was soon assassinated by the chef, and his younger brother Gao Yang succeeded him in 550 to depose the Eastern Wei Emperor and establish the Northern Qi regime.

Gao Yang's father, Gao Huan, joined the peasant rebel army in his early years and later defected to Erzhu Rong. When Gao Yang was born, Gao Huan was not yet developed, his family was poor, and the family was worried about life, at that time, Gao Yang had not yet learned to speak, and even said the word "to live", and his mother Lou Zhaojun was very surprised. When Gao Yang was young, his appearance was plain and taciturn, and he was often ridiculed by his brothers, and only his father Gao Huan was optimistic about him. Later, Gao Huan became the chancellor of Eastern Wei, once he wanted to test the intelligence of several sons, so he sent a bunch of messy hemp to each person for them to sort out, everyone else was silent and buried their heads in tidying up, only Gao Yang drew out a quick knife and cut it down, and soon sorted out a lot of short hemp, which was praised by Gao Huan, which is the origin of the idiom "fast knife chopping mess".
After Gao Huan's death, Gao Cheng continued to control the imperial government, and in 549, while preparing to establish himself on behalf of Wei, he was accidentally assassinated, due to the suddenness of the incident, the imperial court was in chaos, and the obscure Gao Yang stepped forward and quickly calmed down the chaos, and the ministers who had not previously taken Gao Yang in their eyes were surprised, and after the chaotic political situation was controlled, Emperor Wei made Gao Yang the Prince of Qi and the King of Qi. A year later, Gao Yang went to Yecheng and sent Sikong Pan Le, Shizhong Zhang Liang and others to see Emperor Wei and let him give the throne to the King of Qi, Emperor Wei reluctantly agreed, and then he was expelled from the palace, Gao Yang ascended the throne as emperor, and changed the name of the country to Qi, this year Gao Yang was only 24 years old.
After Gao Yang took the throne, the news reached Western Wei, Yuwen Tai led a large army to the east, Gao Yang showed his talents, he gathered the six prefectures xianbei to hold a large-scale military exercise, the mountains and horses shocked Yuwen Tai, and then Northern Qi and Western Wei were at peace during Gao Yang's reign. In the first month of 552, Gao Yang led the Northern Qi army to personally conquer Kumoxi and won a complete victory. In October of the following year, he personally conquered the Khitan and fought all the way to the Bohai Sea, and this battle was very fruitful, and after the great victory over the Khitans, Gao Yang did not have a class division, but took advantage of the high morale to attack the Turks north, all the way to the north of Shuozhou, and the Turks offered their surrender before stopping. A few years of conquest brought the Northern Qi state to its peak.
With the stability of the four directions, Gao Yang's tense nerves relaxed, and he suddenly changed from his original diligence to a tyrannical and absurd prince, who often wore women's clothes and flaunted the market on the street, recruiting a large number of beautiful women for his own indulgence. Gao Yang had a very favored Concubine Xue Gui, who was a prostitute, and Gao Yang suspected that she was having an affair with Gao Yue, one of the Four Nobles of Eastern Wei, and after a drunken drink, he personally killed and dismembered Xue Gui concubine, and also made her leg bones into a pipa while playing and singing "It is difficult to get a beautiful person again".
Gao Yang's mother, Empress Lou, saw that Gao Yang had become like this, so she scolded: "What kind of Lao Tzu there is, there is what kind of son." Gao Yang returned with the strength of wine, "You old woman dares to scold me, I will marry you to Hu Ren." Empress Lou directly fainted. After waking up drunk, he wanted to apologize to his mother, but as a result, He also let Empress Lou fall and hurt, so Gao Yang whipped himself with hatred and determination to quit drinking, but in the end he did not succeed. Gao Yang died violently in 559 at the age of 34 due to excessive alcohol.
Emperor Gao Yang of QiWenxuan, in the early years of Wenzhi Martial Arts, why did he reverse so much during the nine years of his reign, it was completely a dual personality. Gao Yang has been intelligent since childhood, born poor, before the eldest brother Qi Cheng was stabbed to death, he has been hidden, this string in his heart has always been tight, with his usurpation of the throne, the four-way conquest, after proving his ability, he has completely changed into a person, perhaps there is no pursuit, the tight string can never come back after relaxing, who knows.
