The international postal service is generally efficient, and airmail letters and postcards will probably take between five and 10 days to reach their destinations. Domestic post is swift – perhaps one or two days from Guǎngzhōu to Běijīng. Intracity post may be delivered the same day it’s sent.
China Post operates an express mail service (EMS) that is fast, reliable and ensures that the package is sent by registered post. Not all branches of China Post have EMS.
Major tourist hotels have branch post offices where you can send letters, packets and parcels. Even at cheap hotels you can usually post letters from the front desk. Larger parcels may need to be sent from the town’s main post office.
If you are sending items abroad, take them unpacked with you to the post office to be inspected; an appropriate box or envelope will be found for you. Most post offices offer materials for packaging (including padded envelopes, boxes and heavy brown paper), for which you’ll be charged. Don’t take your own packaging as it will probably be refused. You will also need to show your passport or other ID.
