What China traditional culture was castrated in the Qing Dynasty, but it is not seen in the current classics? Have any scholars restored it?

This is not very clear. Judging from the current academic mainstream and political trend, there should be no scholars to restore it at present. Moreover, the "literary inquisition" was established and the "Sikuquanshu" was compiled. My China classics, history, books and collections need more than 200 years to be sorted out, and it is too difficult to restore them.

I think that the castration in Qing Dynasty was mainly the martial spirit and enterprising spirit in traditional culture, which removed the blood and cultivated servility, resulting in closure and backwardness. Many Confucian classics are taken out of context. For example, Confucius's "reporting complaints directly" was promoted as "reporting complaints with good" and so on. The Confucian classics Three Amethyst and The Analects of Confucius were castrated into Twenty-four Filial Pieties and Disciples Rules as teaching materials for children's enlightenment, thus turning the loyalty and filial piety of the monarch into unilateral obedience, bottom-up emotion and foolish loyalty and filial piety. In the relationship between monarch and minister, between father and son, and between husband and wife, there are only unilateral constraints on lieutenant, descendants and women, and there is basically no moral requirement for superiors.

..... In fact, even if it is difficult to recover, there is no need to dwell on the past and care too much. Integrity, know manners. Although China has suffered a lot, as long as China is immortal, it will be able to rebuild the glory of Han and Tang Dynasties one day. More classics were born.
