My brother, the useless prince, is crazy. After being deposed as the crown prince by his father, he hid in his study and read his storybook all day without seeing anyone. On the day when the fifth brother ascended the throne, the deposed prince rushed into the hall holding a piece of paper. He shouted to Fifth Brother: "I am the legitimate son, you are the emperor, and I want to betray you!" In his hand, he held a self-made deed with Fifth Brother's name written on it. The fifth brother had a dark face and asked me to pull the useless prince brother down. I finally believed that he was really crazy.
