What class were the progressive thinkers in Ming and Qing Dynasties? Were they anti-feudal?

Of course, it is still the landlord class.

Huang Zongxi, Gu, Wang Fuzhi and others are the representatives of China's people-oriented democratic thought in Ming Dynasty.

In his political monograph "Ming Yi to be visited", Huang Zongxi pointed out that the monarch who "kills the liver and brain of the world and scatters the sons of the world" and "destroys the marrow of the world" is the "enemy" and "orphan" of the people, and declared that "the monarch is a great harm to the world". He denied the feudal dogma that the monarch is a minister and advocated the supervision of the monarch through schools and the rule of law. This kind of school has the function of confessing "political deficiency" and "making public its right and wrong" to the son of heaven, which is similar to modern representative institutions. It is proposed to replace the monarch's "one family law" with "the law of the world" in order to realize the ideal of "governing the law first and then governing the people". Wang Fuzhi's "not taking the world for his own use", Gu's "multi-governance" instead of "sole governance", and expanding the power of guarding orders in counties and counties are all connected with Huang's thought.
