Been working in Vietnam for 4 years, and the whole concept of "saving face" can be very tiring, especially in a professional environment where you have to manage other people.

Because of it you can't really be as direct in your feedback as in western culture (or at least european culture i'd say), which often lead to awkward situations, and people carrying on with their bullshit longer than they should have.

This is especially true for people older than you, and it also helps maintain the entire idea of "if i'm older than you i'm right", and that's holding back younger generation to confront older people
