Of course the post office can send it! There will definitely be two large mailboxes inside, one for domestic and one for international. Mailboxes are all on the roadside. You can look carefully to distinguish used mailboxes from usable mailboxes: the used mailbox is very old and dark green, with two mail slots on it. The new mailbox in Fuzhou has advertisements on one side and a mail slot on the other, and there is only one mail slot.
