What thoughts did the three great thinkers in Ming and Qing Dynasties inherit from traditional Confucianism?

Li Zhi advocates that the standard of right and wrong changes with the changes of the times, and opposes taking Confucius' view of right and wrong as the standard. Criticize Taoist Zhu's erroneous preaching of "keeping righteousness and destroying human desires" and emphasize people's legitimate selfish desires. It is considered that dressing and eating is "human physics". Without basic material life, people can't talk about benevolence and morality.

Huang Zongxi: Exposed the harmfulness of ignorance, loyalty and filial piety and autocratic monarchy, put forward the democratic thought of "the world is the master and the monarch is the guest" and criticized Confucianism.

C: Practical application. Doubt the monarchy, put forward the rise and fall of the world, every man is responsible. But most of them regard retro as a kind of reform.
