The emperor has a sacred position and supreme power, so no one is willing to give up, even desperately fighting, in history, the struggle between princes is not a minority, and even many powerful ministers hope to be able to seize the throne. However, there are many cases of Zen positions from the perspective of history, but they are generally choices that are forced to be helpless.
Li Yuan, the founding emperor of the Tang Dynasty, was typically forced by his son Li Shimin, and his life after his abdication was not much better, and he was cautious for fear of offending this son.
The same was true of Emperor Li Longji of the Tang Dynasty, who during the Anshi Rebellion, his son ascended the throne himself without informing him, and he became emperor in a daze, and although he was later taken back, his life was not much better.

Those who voluntarily abdicate are different. For example, Qianlong, who still held great power after his abdication, and the Jiaqing Emperor was just a puppet, it can be said that Qianlong's life before and after his abdication has hardly changed.
The same was true of the first three emperors of the Southern Song Dynasty, and although Emperor Gaozong of Song abdicated, Emperor Xiaozong of Song was still very kind to him and very filial. Even after Zhao Zhao's death, he did not have the heart to govern the country, so he also gave the throne to his son, Song Guangzong.
But Song Xiaozong obviously did not have such a good life as Zhao Shuo, and his son was very bad to him. Song Xiaozong took the initiative to zen, why did he live so depressed in his later years?
Song Xiaozong had three sons, originally the eldest son was the crown prince, but he died young, under normal circumstances, he should choose the second eldest, after all, this person is generous, but Song Xiaozong chose the third elder in the past. It is said that Song Guangzong should be grateful to Dade, but he did not expect that the relationship between the two was very tense, even to the point of not interacting with each other.
In fact, there is a reason why Song Xiaozong is depressed.
Song Guangzong Zhao Huan stayed in the position of prince for 18 years, from a flesh-and-blood young man to a middle-aged man with a dull temperament, he himself was not in good health, even worse than Song Xiaozong, so staying up was not the way, but he did not dare to directly let Lao Tzu abdicate, he could only wait like this, but this was not enough to make the two have a gap.
Song Guangzong is really not like Song Xiaozong, he is timid and weak, and he is still a wife and strict. His wife Li Fengniang was personally chosen by Emperor Gaozong of Song that year, thinking that she was good-looking, but he did not expect that this person was very jealous and even had psychological problems.
She was best at separating others, and when Zhao Huan did not ascend the throne, she often complained to Emperor Gaozong and Emperor Xiaozong, saying that the harem was not. Gradually, Song Xiaozong's attitude towards her changed, and Li Fengniang was also dissatisfied with this old man, so she also separated between their father and son, resulting in a gradual change in their relationship.
The most crucial thing is Song Guangzong Lichu. Originally, Song Guangzong had a son, a righteous prince. But Song Xiaozong did not agree, but instead chose the son of the second eldest, although they were all grandsons, but the difference between Song Guangzong and Song Guangzong was great, which made the two sons very angry.
The two did not even go to the Emperor Taishang to ask for peace, and after Song Xiaozong was seriously ill, he did not want to see his son, and even after his death, his son Song Guangzong did not want to come, and even the funeral was not willing to preside.
Of course, the behavior of Song Guangzong's two sons was dissatisfied with the other group of courtiers, and forced him to abdicate at The funeral of Song Xiaozong, and also became the emperor.
