The poor scholar Dong and Dong Wenzhong are twin brothers. My brother Wenbo, the top student in high school, was recruited as Ma Xu, but he was so happy that he came home from his mother's house and fell into the abyss. In the face of Xu's "death", the princess made a painful choice to keep Dong's family prosperous and made her younger brother the number one Xu. Three years later, Wenbo survived, facing the fait accompli, disheartened, thinking about brotherhood, but unable to make public. Unexpectedly, the truth was discovered by the minister of punishments and could not be concealed. Driven by loyalty and luck to the monarch, Wenbo decided to write to the emperor and confess the truth. The news came that there was chaos in Dongfu. In order to protect the safety of Guangrongri and the whole family, the princess and Dong Mu unanimously accused Wenbo of being crazy, but the honest Wenzhong refused to lie. In the golden palace, the emperor and queen saw through the truth, and in order to safeguard the dignity of feudal rulers, they referred to the truth as false. Wenbo finally realized the kindness of his relatives and pretended to be crazy, but he was not acquitted because he was crazy. Instead, the emperor poisoned him. The princess and Dong Mu regretted it and quickly drank the poisoned wine. When Wenzhong arrived, Wenbo had been beheaded as a fake horse. In the face of the tragedy, Wenzhong is really crazy.
