Can I know the taxi fare for 10 person from Beijing capital airport to kuijiachang hutong.

If by taking regular taxi, 10 people need 4 taxies totally. The cab fare is CNY 85 to 95 per taxi.

If you want to take one vehicle, it's suggested to ask help from TravelChinaGuide. They offer airport pick-up and see-off services. You can hire a coaster. The cost is about $113 for the single way. The contact information is bookingtravelchinaguide.com. :-)
