The relationship between An Qingxu and An Lushan (when was An Qingxu killed)

An Qingxu, the second son of An Lushan, the military governor of Pinglu, was a rebellious minister during the Tang Dynasty. He participated in the An Lushan Rebellion and later killed his father to declare himself emperor.
Power is something that everyone loves, and it is precisely because of its supreme power that many people are eager to pursue it. So when we look at the question of why An Qingxu killed his own father, we should set the first incentive for An Qingxu to kill An Lushan as to gain power. After An Lushan launched a rebellion, Emperor Xuanzong of Tang immediately became furious and killed An Qingzhong, the brother of An Qingxu.
Firstly, An Qingxu and An Qingzong must have had a brotherly relationship, so when An Qingxu heard about the rebellion launched in An Lushan and Tang Xuanzong killing An Qingzhong, he would definitely feel sad and complain about An Lushan’s lack of consideration. Secondly, the death of Emperor Anqing was equivalent to elevating his status from that of a second son to that of a eldest son for Emperor Anqing. It is equivalent to making An Qingxu the only “eldest son” who has the right to inherit his father’s position in the future without bearing any shame.
Although An Qingxu was saddened by his brother’s death, it took him another big step on the path to power, which is undoubtedly a gratifying thing. However, An Lushan had a concubine named Duan, who had a son named An Qing’en. Duan was favored by An Lushan and thought of a way to make An Qingxu the crown prince. An Qingxu couldn’t sleep or eat about this matter. Looking at his father’s fierce appearance, he didn’t even know when he would lose his life, let alone his position as the crown prince.
At this moment, the last few words of the dog headed strategist Yan Zhuang played a divine assisting role. He told Prince An that there were some things that needed to be cut off, and the opportunity should not be missed; Tell Li Zhu’er that you can’t count the number of times you’ve been beaten. If you don’t do something special, we’re both close to death. The three of us immediately agreed and decided to kill An Lushan. Under the watchful eye of Yan Zhuang and An Qingxu, Li Zhuer infiltrated An Lushan’s bedroom and carried out a knife killing operation. After the incident was completed, Yan Zhuang and his team dug a deep pit under An Lushan’s bed and buried him on the spot.
