Always, the packets are sent with DHL China, EMS (Express Mail Service by China Post) and AIR MAIL (China Post). You can track packages with tracking numbers on their official sites. But one thing to note is that if the sender chooses AIRMAIL to deliver your package, you can not keep track of them on the official site AIRMAIL when packets have come to your country. Instead, you’ll have to track them in your local post website.
Track the status of their packages on the road is necessary to avoid lost or delivered to the wrong place. If you have lots of shopping in China and Chinese traders, you can easily track your stuff.
