Vietnamese people of the same sex may hold hands or link small fingers when walking as a display of friendship. Direct eye contact is avoided between strangers. Never blow your nose in public. Vietnamese people cover their mouths while eating and talking at the same time. Women may cover their mouths in the presence of a stranger.
Hands Always use both hands when passing an object to another person.
To beckon someone, extend your arm and hand, palm down, and move your fingers in a scratching motion. Only beckon someone of lower status. Never summon someone with your index finger, as is done in the West. This is only done by the boss. Also, do not point at anyone with your index finger.
