As the saying goes, the shooter shoots the horse first, and the thief catches the king first, and what this sentence says is true. However, in view of the problem that the Anshi rebellion could last so long, Tang Suzong did capture the "king", but in the final sense, Tang Suzong still did not understand the real "thief king" of this coup and this civil strife -- what the root of the problem was. If the root cause of the disease is not found correctly and the right medicine is prescribed, then even if An Lushan is killed, this coup will still not be easily stopped, and things will still not get better.
When it comes to the coups d'état of the Tang Dynasty, it is actually a common thing, and these repeated coups d'état in the Tang Dynasty even sometimes involve not only men, sometimes women also participate in them, and even many books can be published with the theme of political turmoil. The Anshi Rebellion is one of the more typical coups, in fact, to ask why the Anshi Rebellion lasted so long, it is better to ask the reasons for the occurrence and continuation of this civil unrest.
The cause of this civil unrest was undoubtedly An Lushan, Tang Xuanzong due to his extreme inaction in the late period of his reign, and it is suspected that An Lushan and Tang Xuanzong had a triangular relationship - Yang Guifei, in short, entangled in various reasons, An Lushan took the lead in rebellion. However, before this, Tang Xuanzong actually received a report from his subordinates, saying that An Lushan was going to rebel, but Tang Xuanzong didn't care at all, and he didn't care at all, which was more fatal, obviously he could strangle the root of the disease in the cradle, but he ended up with a final hunt and killing, and in the end, he could only say that Li Longji was faint and incompetent.
Moreover, in fact, although An Lushan was the initiator of this coup, it does not mean that the initiator died, and the coup could be stopped - An Lushan has a successor, isn't Shi Siming the successor of An Lushan? That is to say, even if one An Lushan falls, there are still thousands of An Lushan who will stand up, after all, who does not want power and money? It is impossible, taking advantage of the country's civil strife, those who feel that they have a chance want to make a profit, not to mention An Lushan's successor.
Another point is that Li Tang's strategy is really not good, looking back at the White Rise of the Qin State during the Warring States period, even if four hundred thousand elite troops have surrendered, people should still be buried, there is no mistake, otherwise this elite team will be put back to the Zhao Kingdom, will they still have to make a comeback in a few years? This is obviously unreasonable, but what Li Tang did was these unreasonable things, not desperate enough. Moreover, Li Tang was obsessed with and obsessed with the capital of the two capitals, and felt that as long as the two capitals were recovered, it would be over, so when after a night of stalemate and the enemy's army withdrew, they would no longer pursue, as long as the two capitals were taken back.
So after a few nights, the enemy's troops made a comeback, defeated, and made a comeback, and went back and forth for several years, and finally it was not easy to calm the war. Therefore, it is not that an An Lushan is dead and the end of the matter, as long as Li Tang does not solve the fundamental problem, there will be more political civil strife such as the An Shi Rebellion.
