Booking a taxi in Shanghai

Well, one taxi doesn't have enough space to put 8 luggage. So you need two taxies.
For one, the cab fare is CNY 160 to 170 in the day time. It takes 30 to 40 minutes.

Or you can find TravelChinaGuide. They provides pick-up service. As I know, the price is also acceptable. You can contact them to know more details. The E-mail address is traveltravelchinaguide.com.
