Is it a cultural lag or a decadent culture?

Cultural backwardness means sticking to the rules.

The difference between cultural lag and decadent culture;

Cultural lag is mainly reflected in traditional culture. Some unreasonable customs, such as some inhuman funerals, and how luxurious the cemetery should be (this is a waste of land resources, which is unnecessary at present, but people have a deep-rooted tradition of burying the dead) are all reasonable and scientific reforms.

Decadent culture is a feudal colonial culture, pornography and gambling are illegal, polluting people's inner culture, and attitudes must be resolutely banned.
