Chen Ping
After Emperor Gaozu's death, Chen Ping and Zhou Bo cooperated to put an end to the Lü Clan Disturbance and restore the Liu clan to power and install Liu Heng on the throne as Emperor Wen. Chen Ping felt that Zhou Bo's contributions were greater than his so gave up his position as the Right Chancellor to Zhou Bo. Emperor Wen once asked Zhou Bo, "How many cases do the courts see in a year?" Zhou Bo was unable to give an answer. Emperor Wen then asked again, "What is the net amount of money and grain the national treasury takes in in a year?" Zhou Bo could not answer the question. Chen Ping, who was serving as the Left Chancellor then, replied to the emperor's queries, "The answers lie with the respective persons in charge. For the number of cases, Your Majesty should ask the Minister of Justice. For the net amount of money and grain, Your Majesty should ask the Accountant of Revenue." Chen Ping also added that he felt that as a chancellor, he should not be in charge of everything, and that the chancellor's role was to assist the emperor by "pacifying all those outside the empire, maintaining peace within the empire and ensuring that all office holders perform their roles well." Zhou Bo was ashamed and felt that he was not as competent as Chen Ping, so he claimed that he was ill and resigned from his post, leaving Chen Ping solely in charge of both the Left and Right Chancellors' duties.
