This is not a curse, this is a warning. I searched this short story for you:
Harry, who was in charge of housework at that time, called on Prime Minister Xu Jie and advised him to give you advice, but Xu did not dare. Harry wrote the book Public Security, risking his life to remonstrate with the monarch for the sake of the country and the people. Hai's wife and friends dissuaded him one after another, and were finally moved by his loyalty and listened to him carry the coffin into the pile of books.
After receiving Harry's letter, Emperor Shizong of Ming Dynasty was furious, threw it on the ground and said to the people around him, "You should arrest him quickly, lest he escape." Eunuch Jin said aside, "This man is a famous bookworm. I heard that when he was at school, he knew that he would die if he offended disobedience, so he bought a coffin, bid farewell to his wife and children, and waited for the crime to enter the DPRK. The servants ran away without staying, so he won't run away. " Later, Ming Shizong took out Harry's official seal and read it two or three times a day. He was moved to sigh loudly and left it in the palace for several months. In the end, he still refused to be scolded by Harry and ordered Harry to be arrested, imprisoned and sentenced to death. Two months later, Sejong died, Mu Zong ascended the throne, and Harry was released from prison.
