China Air Security: Liquids Allowed And Not Allowed

Danwei.org just did a post on the allowability of bringing liquids on to planes leaving China's airports.  The post said liquids have been banned for years, yet I know I was able to bring on a bottle of wine I purchased in a Qingdao airport shop only a few months ago.  The comments to the post were all over the map as to what is and is not allowed. 

I did a bit of research on this and found this Wall Street Journal article, that sets down the rules.  According to this article, "no liquid aside from goods purchased after the airport-security check, like duty-free liquor, could be taken aboard outbound flights. The only exceptions were for baby formula and certain medicines."
