Just today Shenzhen airport pulled my purse for inspection and found the dreaded E-cigs. They thought it was a pen? After they let the items go through there was an announcement on China Eatern that no E-cigs were allowed to be used on the flight. This announcement was not made from Shanghai to Shenzhen. Hmmm. However I did not and would not smoke E-cigs on an airliner in China in public areas, too cautious.
