Why are there such terms as North drift and Deep drift in China?

"North drift" just shows that only Beijing in China is a more "cultural" city.

Then it shows that China (including Beijing) lacks the mechanism and environment of cultural production (including the value orientation of the whole society).

How many young artists and how many "talented people" have no chance, no stage and are even regarded as different. They are also advised by well-meaning relatives and friends to "take the right path" or "seek steady development" because there is no such demand locally (just look at the proportion of cultural expenditure of residents in small and medium-sized towns) and the outside world is very rogue. China's national cultural consumption is TV series, and national sports is mahjong (regardless of men, women and children, this is also the best means of maintaining stability.
