What are the subjective and objective reasons for the disappearance of traditional culture in China?

Objective reasons: China has been bullied by foreign powers since modern times. As the old saying goes, the granary knows etiquette, food and clothing know honor and disgrace, and without a strong economic foundation, how can the superstructure be established? Coupled with the input of various forms of western (especially American-oriented) ideas, many young people are becoming more and more westernized. . .

Subjective reasons: Actually, it is based on objective reasons. As the largest developing country in China, most people live for stability and satisfaction, and have no time to care about their spiritual life. Even if there is, it is also some decadent spiritual pursuit and low taste. .
