If you are traveling from Changzhou to Shanghai Pudong International, new and extra security measures are in place. This came about because of an explosion that occurred at a ticket counter. Somebody lobbed a crudely constructed explosive, and four people became injured because of it.
In all honesty, this new security check didn’t take much time. I recently flew out of Pudong while on my way to New Jersey to see my family for about 13 days. When I went through this checkpoint, I had walked from the Maglev station to the terminal containing United Airline’s ticket counters. Once I reached the check point, I saw that they were wanding ten people at a time. This was to speed up the flow of travellers. By wanding, I mean security officiallys rub a piece of fabric over everybody’s luggage and bags. If an alarm is tripped, then they will more than likely check people within that group individually.
