Emperor Myeongjinzong reigned for 48 years, the longest reigning emperor of the Ming Dynasty. However, after 14 years of personally presiding over state affairs, he actually stopped participating in state affairs and neglected state affairs for 20 years. As an emperor, it was his duty to rule the country, but why did The Ming Dynasty ignore it for 20 years? Some people say that Zhu Yijun began to indulge in wine. Some say he was addicted to opium, but more people believed that the reason for the quarrel between the emperor and the cabinet over the appointment of the crown prince was that he had not left the palace and ignored the government.

At the age of sixteen, the empress dowager's ministers elected Wang and Liu as empresses and concubines. However, the rebellious Zhu Yijun did not like such a strong marriage at all, let alone the empress and the concubines, so he was very cold to these two wives. When Emperor Shenzong was 20 years old, he accidentally gave birth to a son with a palace maid. At that time, when the empress in the palace did not give birth to her first son, she was listed as a prince according to the custom, but later Shinjong met the confidant of the red face that he loved the most in his life. Zheng was originally a palace maid who won the favor of the emperor because of her beautiful appearance. She was soon honored as a noble concubine, and the two admired each other and could not be separated for a moment. Four years later, the third son of the emperor was born, and the emperor was very fond of the newborn child. He directly promoted Zheng Guifei to a position second only to empress. At the same time, the emperor wanted the emperor's third son to become the crown prince. The idea of "son preference" was opposed by the magnates, who believed that the abolition of elders and the establishment of children were contrary to patriarchal etiquette. In order for the state to make the emperor's eldest son a prince, the opposition of the courtiers overwhelmed the Cult and had to be vigorously suppressed. When the empress dowager found out, she began to question Emperor Shenzong, but Emperor Shenzong delayed the appointment of the crown prince in a delayed manner. In order to establish a prince, the emperor and all his courtiers fought each other, and those who could not be suppressed were greatly annoyed. Later, the emperor adopted the method of not going to the court, passively confronting the ministers. Moreover, the bureaucracy worked because no imperial cabinet functioned as usual. If things go on and the emperor does not approve, it means a breach of contract. Whoever said that he wanted to be crown prince would automatically invalidate the classics, and the outside world would not know the truth. It was not until the twenty-ninth year of the Wanli Calendar, that is, in 1601, that Emperor Shenzong feared that if something happened in China, he would fall into chaos, and for some other reason, he had to appoint Chang Luo as crown prince, and this protracted struggle for the founding of the state was finally over.
In fact, at a deeper level, the main reason God could not live in court was the violent conflict between imperial power and the civil service. Imperial power was suppressed. Zongshen fought it in a negative way, but there were two points that were still worth affirming. First, Emperor Zongshen did not kill people because of the insults of his ministers; second, he did not go to court or stop working. All the major and minor affairs of the Wanli Emperor were handled by Zong Shen.
