Gao Changgong's death: One day in 565 AD, when Gao Wei and the warrior Lan Ling talked about the victory of Mangshan, he said, "It's a pity to enter the war too deeply and lose." The soldier Lan Ling was excited and enthusiastic when he heard that his brother was so distressed by himself. He replied affectionately, "My family is good, but I don't feel it." It was this expression of intimacy and loyalty that led to his death. The history book says, "The emperor disliked family matters, so he avoided them." Because in the eyes of Gao Wei, the narrow-minded ruler, family affairs are my Gao Wei's, not something you casually say. I began to wonder whether the warrior Lan Ling, who has the military power, wants to replace it and turn "state affairs" into "family affairs". After the warrior Lan Ling said the wrong thing, he was deeply troubled and worried all day long. Although he has repeatedly kept a low profile and deliberately played down himself, he can't escape the tragic fate of "if you tell me to die, I have to die". One day in May in the fourth year of Wuping (AD 573), the late Lord Gao Wei sent an envoy to visit his brother Gao Su, and the gift was a glass of poisoned wine. The warrior Lan Ling was so angry that he said to his beloved Princess Zheng, "I am loyal to my work, and I am embarrassed by heaven!" Zheng Fei advised him, "Why don't you ask God?" Naive Zheng Fei thought it might just be a misunderstanding between brothers. As long as Gao Su intercedes with the emperor, he can get his own life back. And the warrior Lan Ling himself knows that it is useless to find a backward master to explain. A year ago, Hu Luguang, a etiquette veteran who fought bravely with himself, was also innocently lured into the palace and brutally strangled with a bowstring. In despair, the soldier Lan Ling left a sentence, "How can I see the beauty of heaven?" So he gulped it down and resolutely left this messy world. Burn all the bonds before he dies. At that time, the warrior Lan Ling was only 30 years old and was buried in the capital city of Yexi (now Linzhang County, Handan) after his death. The killing of the military commander Lan Ling marked the end of the Northern Qi Dynasty. Four years later, the Northern Qi Dynasty, which lost its military pillar, was destroyed by the Northern Zhou Emperor Yu Wenyong, and almost all the descendants of Gao were slaughtered.
