1, ancient Chinese medicine has made progress now. Now Chinese medicine is closer to modern science, and modern medicine is more standardized than ancient Chinese medicine. If you encounter severe Chinese medicine, the effect will be immediate. Unfortunately, there are fewer and fewer good Chinese medicine practitioners in society.
China Kung Fu was certainly more prosperous in ancient times than in modern times, because there were many wars in ancient times and people practiced martial arts. But now is the era of peace, the era of hot weapons, the government does not support martial arts, and martial arts practitioners will not fight for their lives. It's all about making money, not as good as in ancient times. Traditional Wushu is declining and degenerating into aerobics, such as Tai Ji Chuan. My teacher said that the inheritance of Wushu in modern society is more closed than that in ancient times, and few people get the true story. I studied martial arts with my teacher, and both of them wrote letters of guarantee, promising not to spread our knowledge, theory, explanation, experience and methods. You don't teach people casually without the teacher's permission, and you don't teach people purely for money. Zhenmen attaches great importance to secrecy. It doesn't matter if it's not a real descendant. These things can't be found on the Internet at all, and the articles and videos that are disclosed on the Internet to decrypt China Wushu are not to the point at all.
In terms of Chinese etiquette, modern society should have new etiquette, not in the ancient way.
The three aspects you mentioned, except martial arts, can't be said to be faults, but are impacted by modern cultural science, which makes people feel worse than before. The inheritance of martial arts is indeed becoming more and more closed. There is something wrong with the idea of going abroad. This is culture, not money. It cannot be said that China's own national culture will be accepted by other countries.
