Face (miànzi) and guanxi (guānxi, connections) are the two keys to Chinese social life.
What Is Face
Face is dignity, reputation and social standing. Public criticism makes someone "lose face"; praise and respect win it. Giving face builds rapport fast.
What Is Guanxi
Guanxi is a network of mutual obligation and trust. Things get done "through connections," maintained over time by favors, meals and reciprocity.
Tips for Learners
Avoid embarrassing people in public; give criticism privately and gently; reciprocate favors; join group activities to build trust.
In a Nutshell
"Give others face, and guanxi follows."
