This is a very worthwhile place to go, a city. Leave a memory. If a friend has a chance, he can go and see it. What do you say? Because I feel there is a very distinctive and artistic atmosphere here.
Come to Chengdu and visit the Panda Post Office, because it has a special postal code and postmark that is not available elsewhere. It has exclusive stamps and first-day covers. It's also a good choice to buy a few stamps and send them to your friends.
