旧脸社会

The phrase '旧脸社会' (Old Face Society) refers to a society or social phenomenon where people, especially in public or online contexts, maintain an 'old face.' This could mean adhering to old customs, presenting oneself with a certain level of formality and restraint, or it can even imply the use of long-existing methods or appearances that haven't changed much. The term could reflect nostalgia, tradition, or criticism of unchanging societal attitudes.
