I see a picture today, I will post it below. It shows how do Chinese people express numbers by gesture. I mean easily most people use fingers on one hand to represent numbers from 1 to 5, but how to express 6 to 10 on finger gesture? I have seen some military or SWAT hand signals, they can represent 1 to 10 by only one hand, but that is not the way we do every day.

This picture shows exactly what people show you 1 to 10 by one hand only. Maybe in some area it has little different, like I express 10 by make a fist(coz I want to use one hand), but that is what I see people do in Nanning.

How do you do this in your places?
