1, don't want to kill. Zhu Yunwen didn't want to kill Judy. Zhu Yunwen grew up in the palace, received a strict Confucian education, and had no combat experience on the battlefield. He was gentle, generous, cowardly and kind. He valued Confucianism's benevolence and morality most, so he didn't do anything to kill his uncle Judy. ?

2, dare not kill. Although Zhu Yunwen's attack on the vassal was aimed at Judy, the most powerful vassal of Yan, it was obvious that Judy's strength far exceeded that of Zhu Yunwen, and Zhu Yunwen did not have Judy's courage and strategy, so Zhu Yunwen did not dare to kill Judy. This situation led to Judy's growing strength, which led to the battle of Jingnan.

1, Zhu Yunwen improved the strict legal system implemented in Ming Taizu. Emperor Hongwu once promulgated a set of codes, which became the legal norms of the whole empire. He sometimes supplements the code in the form of patent certificate, and sometimes publishes typical cases in the form of "list". The announcement first appeared in Dagao; This height is compiled, modified and expanded between 1385 and 1387.

2. Zhu Yunwen also carried out some reforms on the fief management of princes: Fu Bin and Bandu were established, and the Hanlin bachelor was allowed to educate and coach young princes with Confucian tradition. The prince was further forbidden to participate in civil and military affairs; This order is obviously quite different from the provisions in Zu Xun Lu. These new regulations strengthened the emperor's control over the vassal king and were part of the overall strategy aimed at abolishing the semi-autonomous fiefs of the country. ?
