The imperial court summoned hundreds of officials to the Ministry of Punishment to discuss the formulation of criminal laws. Everyone believes that anyone who embezzles more than two hundred yuanbao notes will be punished by death. Zhao Mengfu thought it was too heavy, because in the decades after the establishment of the banknote law, it had depreciated significantly, and it was not enough to use depreciated banknotes to decide people's life and death. Some people saw that he was young and came from the south and did not understand the national conditions of the Yuan Dynasty. They accused him of opposing the use of Yuan banknotes to convict people because he wanted to hinder the popularity of Yuanbao banknotes. Zhao Mengfu retorted confidently, pointing out: "Criminal law is related to life and death of human life, and the severity must be distinguished. Zhao Mengfu participated in the deliberations under the imperial edict and dared not say anything. You are unreasonable and try to use your power to suppress others. This will not work!" People are speechless.
