How to distinguish between cultural backwardness and decadent culture?

Cultural lag: all kinds of superstitious, ignorant, decadent and vulgar cultures are cultural lag. Cultural backwardness is often manifested in the form of traditional customs, such as fortune-telling, fortune-telling, word-testing, feng shui and so on. Cultural lag is a kind of cultural dross, which needs to be reformed and eliminated through scientific and cultural education.

Decadent culture: it corrodes people's spiritual world, erodes national spirit, hinders the development of advanced productive forces and harms the socialist cause. We must resolutely resist it and ban it according to law.
