In Eastern culture, making someone lose 'face' is one of the worse things you can do, especially publicly.
They take it quite seriously, it's a big part of their culture, that's why they don't really question seniors, elders and teachers, not so much from respect but due to face, they don't want them to lose face, especially in public.
I'm generalizing a bit here now, but they can care more about their image to others and how they come across, rather than actual substance. Image is very important, possibly the most important thing for them.
