Photography crowdfunding. Someone from the postal service said that they can make postcards. Is it reliable? On the crowdfunding website "Spring of All Things in China"

You can DIY postcards at all China Post business offices. You can print out postcards on the spot using your own photos and pictures you brought. In addition to postal business offices, postcards produced in various other ways and postcards sold by non-postal offices are likely to be fake. Because the postcards produced and sold by the postal service office all have postage, other postcards are not eligible to be produced and have postage attached, and the postal system will not deliver them.

The picture above is the postal newspaper and letter sorting and delivery room. The sorted newspapers, periodicals and letters, including postcards, are delivered to the user's home by the courier.
