The other day, the department secretary attempted to mail copies of Architectural Worlds and two packs of playing cards to a friend in Switzerland. The journal went through, however, the cards did not. The reason given was that it is illegal to send playing cards through the post because they are used for gambling. Who knew?
It is legal to print, transport, and sell playing cards in China. Indeed, there are decks designed specifically for collectors. But there are no decks of cards in Chinese post offices — except perhaps for those in the hands of postal workers who are relaxing over a game or two!
According to Item 37 of the Chinese Postal Code (第三十七条 任何单位和个人不得利用邮件寄递含有下列内容的物品) the list of seven types of materials that cannot be mailed are: (1) treasonous materials; (2) state secrets; (3) false information that contributes to social unrest; (4) materials that inflame inter-ethnic hatred; (5) propaganda on behalf of cults or superstitions; (6) smut, gambling, and terrorist materials, and (7) any other content that is not in compliance with Chinese law. The complete postal code, along with the list of items that cannot be shipped in the Chinese post is online.
