Why can't the essence of China culture be passed on?

All the factors that determine things are people. Over the past half century, our country has taken too many detours and encountered too many setbacks. Poverty and backwardness have not been completely solved. China people's poor quality of life and low level of education lead to low self-confidence, so that they deny all traditions and think that foreign countries are good. Traditional things are dross and cannot be passed on.
