Should we abandon traditional etiquette?

We can't completely abandon traditional etiquette, which has a lot of valuable contents, but we can't completely inherit it indiscriminately. After all, it is a legacy of thousands of years of feudal society, and there are some bad things. Moreover, China's traditional etiquette, as an important part of traditional culture, is also an important embodiment of China's traditional culture, which is different from western culture. Therefore, there should be selective inheritance.
