1. I hope somebody explain to you what was the type of parcel was sent to you, if not, you might want to read this:

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.

SAL: short for Surface Air Lifted. Ships, buses, and trains are used within the sending and receiving countries, but air transport is used between countries. Land and sea transport are used if there are no flights. Usually it takes 15 – 20 working days. The cost is lower than air mail.

SURFACE: a parcel is transported via land and sea transport. It is cheap, but takes 40 – 70 working days.

2. This is a tracking I found for you:
