What is the traditional culture of China? Why should we promote traditional culture? Why is China's traditional culture missing now?

Such as the Forbidden City, Beijing Siheyuan, Peking Opera, paper-cutting, shadow play, baking and painting. , is the traditional culture of China. Now these things are very few, and with the development of society, these precious skills may disappear.

On the one hand, it is for the continuation of these things, on the other hand, it is for people to understand. Otherwise, isn't it ridiculous that China people don't even know what their traditional culture is?

As for the lack, we should know that most of the skills in the past were handed down by a single pulse, and some were just gone. But many of them were lost in the war, and Mogao Grottoes is an example.
