Today, Emperor Yuwen from next door came to me to communicate with me. After a few glasses of wine, he started crying about the unlucky children in his family who fought so hard for the throne that he lost his conscience. The second prince, who was the most scheming, had all his eldest brother and three younger brothers deposed, and was just about to force him into the palace. At the end of the sentence, Lao Yuwen did not forget to pat me on the shoulder and said sincerely, Xiao Chengyuan, you must establish the prince as soon as possible and make more preparations to avoid instability in the people.
