1. This is what I found for you:
format 2: the number starts with “CP” and ends with “CN”, i.e. CP123456789CN
This is China Post registered surface mail. Normally it is much slower than airmail and might take up to 6 months to arrive.

2. You can find the info here:

What are the stand formats of China Post tracking number? How to distinguish them?

Hope this help.
