Restaurant

A bit!
In English, we have different ways to talk about a little bit of a thing or an action; for example, Wait just a minute or Take a (quick) look! In Chinese, it’s common to use 一下 (yíxià, a bit). Check it out!
请等一下
(Qǐng děng yíxià.) Please wait a moment. (literally) Please wait a bit.

(Qǐng kàn yíxià.) Please take a look. (literally) Please look a bit.
How many?
When asking about smaller numbers use (jǐ), which means How many? And don’t forget to use a measure word!
请问几位
(Qǐngwèn, jǐ wèi?) Excuse me, how many of you?
他们几个孩子
(Tāmen yǒu jǐ ge háizi?) How many children do they have?
How many of you?
(wèi) is used as a measure word instead of (ge) when asking How many people? in a formal setting (for example, when you are greeted at a restaurant). Notice how (wèi) is also repeated in the exchange below.
