How to treat the decline of traditional etiquette in modern China and the recent rise of retro Hanfu and ancient etiquette? Self-understanding and opinions

Personally, the reasons for the decline of traditional etiquette are as follows: first, the life of traditional etiquette was top-down in the Republic of China, and bottom-up in the May 4th Movement (the traditional etiquette at that time represented the feudal system); Second, the pace of life is accelerating, and traditional etiquette is completely inapplicable.

The recent upsurge is also adapted to the development of society, representing a slow-paced life and a bottom-up recognition of China's traditional culture. But personally, I think this trend is superficial, and people with excellent real cultural background are in the minority. Generally speaking, the advantages outweigh the disadvantages, but we need a real expert as a representative, not an online celebrity.
