Why didn't a woman take charge in the Ming Dynasty, and how many masters were there? Is it because women were stupid at that time? Or is it a system problem?

From the beginning of its establishment, the Ming Dynasty fully absorbed the lessons of the previous generation of women in charge of politics and began to prevent the emergence of women in charge of politics from the system design.

The most important design is that all concubines are selected from ordinary well-off families, and it is not allowed to choose concubines from aristocratic families. The concubines and concubines thus elected had no power and foundation in the imperial court, and could not interfere in the political affairs of the imperial court (the important factor for Qi to interfere in politics after the Han Dynasty was that the concubines and concubines were too powerful). In addition, women from small families basically have no chance to receive training in political struggle, so in the history of the Ming Dynasty, although some empresses can spoil the harem exclusively, they were rated as "street girls" (for example, Wan Guifei in Ming Xianzong) on the level of political struggle. This system design can basically put an end to the possibility of empresses entering politics.

Secondly, the Ming dynasty had strict restrictions on nobles: the founding fathers were basically killed by Zhu Yuanzhang; Non-lineal members of the royal family are strictly confined to fiefs, which is almost like house arrest; Empresses and concubines have customized rewards that only Marquis can receive, but she has no right to enter the DPRK. When the civil service system reached its limit (the Ming Dynasty also tried to strictly limit the eunuch's power, but it was actively destroyed by several later emperors), the civil service system had its own system, and it also fundamentally opposed aristocratic intervention. Under the civil service system, it is difficult for the aristocratic forces in the Ming Dynasty to form aristocratic politics like the Han and Tang Dynasties, which is basically isolated from politics. In this way, it is difficult for empresses to form an alliance with nobles, and even if they become nobles, their families cannot intervene in government affairs.
