Talk about your views on Li Longji and Yang Yuhuan

People always say that the tragedy of the love between Emperor Ming of the Tang Dynasty and Yang Yuhuan was due to Li Longji neglecting government affairs and appointing treacherous villains. Concubine Yang was also domineering, and one person got a chicken and a dog to ascend to heaven. An Lushan took advantage of the opportunity and launched a rebellion. In my opinion, their love tragedy is also partly caused by bad luck. Just think, throughout the ages, how many emperors have not had beauties? Which emperor does not love both the country and the beauty. Well now, whenever they hear about a rebellion or destruction in an emperor's era, some people insist that it was caused by that emperor's indulging in the harem and not caring about state affairs. From a historical perspective, human beings are constantly moving forward. From primitive to slaves to feudalism to capitalism to socialism, it is inevitable. Who can say that the destruction of a dynasty is not a good thing? On the other hand, it Promoted historical progress.
