The "Party Struggle" between Wei Zhongxian's "Strict Party" and Lindong Party has always been regarded as an important factor leading to the demise of the Ming Dynasty. Lindong Party, which originated in the middle and late Wanli period, is a bureaucratic and political interest group with Jiangnan literati as the main body. Because Gu Xiancheng, Gao Panlong and other party leaders gathered in Wuxi Donglin Academy to give lectures, it was called Lindong Party. Lindong Party is flaunted by the traditional Confucian moral concept, and often carries out activities to comment on various national social and political hotspots, and takes "family affairs, state affairs and what's going on in the world as its own responsibility" as the slogan, controls public opinion and participates in political activities. The participants of Lindong Party are mostly big bureaucrats, gentry landlords, big businessmen and other groups. The interest groups formed by these people are strongly exclusive to the outside world for the sake of safeguarding their own interests, pushing a large number of bureaucrats and scholars who lost in the competition with Lindong Party to the other opposite side.

To defeat Lindong Party, we must find a backer and a companion tree. Throughout the empire, the only one who can compete with Lindong Party is the "eunuch". The political system of "emperor-civilian cabinet-eunuch in charge of ceremony" formed in the middle of Ming Dynasty made eunuch in charge of ceremony become a political force on an equal footing with cabinet university students. As a result, the bureaucratic gentry who opposed the Lindong Party took refuge in Wei Zhongxian's door and formed a powerful "Yen Party Group". The struggle for rights between the two parties, regardless of the sufferings of the people and the rise of the Eight Banners in Manchu Dynasty, is far less noble than the other party.

From a big perspective, Lindong Party and Yen Party are vested interests, and they are keen on accumulating social wealth. The struggle between the two parties is largely a struggle for interests and wealth, and it is a typical infighting within the ruling class. At the beginning of Chongzhen's accession to the throne, Wei Zhongxian was quickly expelled, marking the official disintegration of the Yen Group. From then on, Lin Dong was the only one. They pretended to oppose Emperor Chongzhen, amassed a lot of social wealth against Emperor Chongzhen, and aggravated the social contradiction of the polarization between the rich and the poor in the empire. During the turbulent period of Ming and Qing Dynasties, they clutched their pockets tightly and searched for spokesmen of big bureaucrats, big landlords and big businessmen among Chongzhen, Li Zicheng and Dourgen. At the moment when the Hong Guang regime in Nanming surrendered to the Qing army, the leader Qian said, "The water is too cold", which revealed the true face of Lindong Party, which only cares about money. ...
