I don't think it's real. Tea ceremonies, calligraphy, screeching opera, the four books and the five classics, it's all a lie. They are "culture" in the same sense opera and ballet are in Europe. They are performed arts, refined in particular directions, expensive, and shared by some as entertainment. Confucianism, for instance, isn't Chinese culture at all. It's a ruling philosophy pasted over a collectivist peasant culture.
I read in a book there were popular forms of "opera" in China, open to the public and performed (maybe) in villages. I do see groups of musicians out in public squares clanging out that wheedling, whiny "traditional" style (which, in a certain light, is pleasant and interesting). But this refined nonsense with five thousand years of backups? I do not believe. Among other things, the language of scholars and gentlemen was, for most of those five thousand years, not the popular tongue. The idea that the elites should speak and write the same way as normal people is a recent invention.
What's the real culture?
