I had to fly to Shenzhen yesterday. Well, kind of. You still can't REALLY fly direct to China from Taiwan, so I flew to Hong Kong and then had a car drive me to the Shenzhen hotel.
The crazy thing about the journey was this: the immigration check-points are drive-through. As in, you hand your passport and immigration form through the car window - first on the Hong Kong side to leave and then on the China side to enter - and then smile really big while the officer looks at your picture and then at you and then at your picture...
Five minutes, tops. And I didn't even have to get out and stand in the humid South China air. Um, yes, I would like an order of fries, a Big Mac, oh and permission to enter China please.
