A big custom is asking if someone is hungry by saying "chry bau le meiyou" because you don't want people to go hungry. Of course you want to say ni hau mau (how are you), or ni hau (hello), Zao (morning), and Ching tzou (please sit).When being introduced is just the same things like shaking hands or smiling and nodding your head, and even a slight bow shows respect to someone.

 While writing/ saying a name would start with the last name then the given two or one syllable first name. friends/aquantinces just say by full name in order.
