The specific reasons are as follows:
(1) East Factory: In the 18th year of Yongle (1420), in order to suppress political opposition, Judy, the Ming Emperor, decided to set up a new official position, named "Dongjingchang", which rebelled against Taizu's ban on eunuchs' interference in political affairs and made him a leader. The establishment of the East Factory also has the intention of monitoring the Royal Guards. The deeper background of the establishment of Dongchang is the strengthening of centralization in Ming Dynasty.
(2) West Factory: the full name is "Xiji Factory". Emperors such as Yingzong, Jingdi and Xianzong. They are all stupid and incompetent, and they don't care about state affairs for a long time. Eunuchs seize the opportunity to steal power, so courtiers and eunuchs are also fighting for power and profit, and the contradictions and struggles within the ruling group are becoming increasingly fierce. In order to maintain the supremacy of imperial power and effectively control courtiers, the emperor began to adopt a new method of supervision and control, that is, to set up a secret service agency to secretly monitor courtiers' words and deeds through trusted eunuchs, so the West Factory came into being.
Extended data:
Dongchang, Xichang and Wei Jinyi were the secret service agencies set up in the Ming Dynasty outside the three judicial organs, namely, the Ministry of Punishment, Duchayuan and Dali Temple. They were directly subordinate to the emperor and were in charge of the "royal prison".
Like the East Factory, the members of the West Factory are all selected from the Royal Guards. The number of Xuaner (that is, a captain of the Royal Guards) in the West Factory led by Tang Xianzong is twice that of the East Factory. The functions and powers of the East Factory and the Royal Guards have all been taken over, and their functions and powers are greater than those of the East Factory and the Royal Guards.
