72 Hour Visa free transit European Country

I think you can enjoy 72 hours free transit in Shanghai. Usually, the airlines will ask the passengers if they want to do 72 hours free transit. If they don't, you have to tell them at least 30 minutes before the plane lands. It's very easy. When you follow the signs to pass the checkpoint, you will get sealed on your passport if you meet the requirements. It doesn't take much longer time.
