Why did Cao Nai die tragically in the army in Ming History?

According to historical records and Cao Zhi's genealogy, Cao Nai was behind Cao Liyong, the minister of the Northern Song Dynasty, or Cao Bin, the founder of the Northern Song Dynasty. In the first year of Xuande, Cao Nai took the second place in the post-school, and was appointed as the discipline of Daizhou. Later, he was assigned to Taihe County, Jiangxi Province to do typical history. Until the eighth year of Xuande, at the age of 3 1, he was officially admitted as the first-class champion, commonly known as the "champion". The title of number one scholar gave Cao Nai a lot of aura. Of course, the political clarity in Xuanzong period of Ming Dynasty also provided him with favorable soil. After all, this period was the famous "Benevolence Metaphysics" in the Ming Dynasty. After Ming Yingzong acceded to the throne, he was too young, so the affairs of state were handled by Empress Dowager Zhang, who relied on his power to disregard his family and relatives. She appointed the "Sanyang Cabinet" to be in charge of political affairs.

The famous "Sanyang" is a veteran of the four dynasties and has a very high status. With such a person, Cao Nai's career will be smoother. During the five years of orthodoxy, Cao Nai was recommended by cabinet ministers Yang Rong and Yang Shiqi to enter the Wen Yuan Pavilion for maintenance. But Yang Rong died soon. Yang Shiqi can't be business as usual, and most of the cabinet affairs are handled by Cao Nai. 1444, Yang Shiqi also died. 1445, Cao Nai graduated as assistant minister of official department with a bachelor's degree in Hanlin. 1446, the last Yang Pu in Sanyang died. In this way, in just a few years, the era of "Sanyang" in the Ming Dynasty is gone forever. 1447, 44-year-old Cao Naicheng set a new record in the Ming Dynasty.

However, compared with the previous Sanyang, Cao Nai is much worse in both qualifications and fame. Cabinet members became vassals and puppets held hostage by eunuchs. Of course, it's no wonder that Cao Nai. In fact, as early as when Wang Zhen was favored, he began to interfere in political affairs. After the death of Empress Dowager Cixi Zhang, the status of the cabinet was greatly worse than before. The choice to start making waves did not attract the attention of the cabinet. In fact, this time has been a little overwhelmed. Although the cabinet records that Cao Naiqiang strongly opposed personal expedition and thought that he was not completely sure, Ming Yingzong obviously thought that Wang Zhen was a eunuch. In this way, in a haze, Zhu Qizhen and Ming Yingzong hastily assembled 200,000 troops and set off. Although Cao Nai was in the army, Britain had an emperor and Wang Zhen, so he didn't have much chance to speak. As a result, the emperor was captured and Cao Nai died in a scuffle.
