Why can the most divine prince in the Tang Dynasty accurately predict the weather? Why did the king cry when he told the reason?

The prince's name is Li Shouli, because he lived a hard life when he was young and was beaten with a stick, which left him with serious sequelae. He will feel uncomfortable when it is going to rain, and he will relax when the sun comes out, so he can accurately predict and forecast the weather. Li Shouli is Tang Xuanzong's cousin. After listening to his reasons, the king knew that he had had such a painful experience, so he felt sympathy for Li Shouli's experience and burst into tears.

Li Xian, Li Shouli's father, is the most outstanding son of Wu Zetian. In 675, after the death of the prince, Li Xian was made a prince. During his tenure as a prince, he achieved remarkable achievements and enjoyed a high reputation. Therefore, it attracted the fear of Wu Zetian. Wu Zetian was afraid that Li Xian was too good to stand in her way. Even his own son Wu Zetian brutally abolished Li Xian, and then Li Xian was exiled with his son Li Shouli.

Li Xian was finally forced to commit suicide, and only his son Li Shouli survived. However, Li Shouli's life as the son of a sinner must be hard. He doesn't even have a thick coat in winter. Moreover, during the ten years of exile and imprisonment, Wu Zetian sent someone to punish his grandson Li Shouli every year, and every time he was beaten, Li Shouli was scarred. For these reasons, Li Shouli left a serious sequela.

Every time it rains, Li Shouli feels a dull pain in his back, and every time it comes out of the sun, he feels relaxed. It can be seen that this weather forecast was earned by his hard work. If possible, I don't think Li Shouli wants this kind of "magic". In ancient times, it was common for emperors to kill their closest relatives for the throne. For the sake of rights, they do not hesitate to cruelly hurt their sons and grandchildren, even their fathers. How happy we are to live in modern times!
