It’s usual to shake hands when meeting someone. A few people may cover their heart with their hands and nod. Close friends of the same gender will hug and may kiss one another on the cheek. However, men and women never offer to shake hands, nor will they speak to one another in public. Furthermore, avoid eye contact between men and women. Men may briefly make eye contact with one another.
Asking a direct question immediately after meeting is considered to be rude. It is important to first ask after the other person’s health, family, and other domestic areas of life.
