I can't understand about cryptography. What is it mean? I search on internet abount cryptography but I can't understand.

How did you try to understand it? Have you tried viewing videos or something similar?
I personally learn everything through the internet and I can say most of the times there are a lot of resources that can give you great insight about the topics that you wanted to learn.

Which site that you use to learn about cryptography? What kind of understanding that you want to achieve? Just to know what is cryptography or learn how to do it?

If it's only about definition, Wikipedia should be able to help you: https://en.wikipedia.org/wiki/Cryptography.
