It's been 2 1 century now. Why are there so many people with feudal ideas?

The feudal reasons of people's thinking now: First, influenced by the ancient feudal thought period, in fact, the feudal residual poison has not been completely eliminated! Second, people's thoughts have not been civilized, enlightened, evolved, and completely liberated! China people's thoughts, especially rural people's thoughts, are still very ignorant and pedantic, and have not developed in depth at the "spiritual" level! Most people in China have no ideological realm! No sense of self! Everything is easy to change, but "thinking" is the hardest to change. The establishment and development of ideas is the longest and the most difficult. Our country's feudal ideology has lasted for thousands of years, and it has only been a few decades since the reform and opening up. It is impossible to change it so quickly! From our parents, grandparents and their generation, we can clearly feel the thick and heavy feudal tradition, and people's thoughts are imprisoned and restricted! They only know the three cardinal guides and five permanents, three obedience and four virtues! Deeply rooted! Advanced thinkers can't understand why there is a generation gap between young people and the older generation. This is the source!
