"After you 100 years old, your throne will be passed on to your brother. After your brother 100 years old, the throne will be passed on to Zhao, and after Zhao 100 years old, the throne will be passed on to his descendants. The world is so big and the government affairs are so complicated. Only by making an able old man emperor can Zhao be saved! " Du Taihou saw clearly the essence of Zhao Kuangyin's proclaimed himself, and reminded Zhao Kuangyin not to make the same mistake.

Zhao Kuangyin originally had five brothers, but in the process of growing up, his eldest brother and younger brother died unfortunately. Therefore, his half-brothers are only three, namely, and Zhao. Zhao Kuangyin is a very clever and ambitious man. As his eldest brother, he has been wandering alone since he became an adult. Zhao Kuangyin hopes that he can achieve something in his lifetime and pay tribute to his ancestors. Generally speaking, ancient people all started from a pawn, and Zhao Kuangyin was no exception. He started from a nobody and gradually developed into the commander-in-chief of the whole palace.

Zhao Kuangyin's second brother, Zhao Guangyi, made great contributions to Zhao Kuangyin's claim to the throne. It was Zhao Guangyi's idea to put Zhao Kuangyin in the yellow robe. At that time, Zhao Guangyi organized his own imperial generals to discuss this matter together. In the discussion, he pointed out the way to get rich for imperial soldiers. He thinks that the present emperor is incompetent. For the long-term stability of the country, they must make a capable man king. When all the soldiers heard this, they all agreed to Zhao Guangyi's suggestion and asked King Zhao Kuangyin.

Zhao Kuangyin got the throne only because the king at that time was young and ignorant. Empress Dowager Du's words inspired Zhao Kuangyin to see the essence of the throne.
