Hi Asha,
Greeting from Peggy, Top China Travel
I'm sorry do you mean you are looking for a travel agent which can arrange a group tour for students started from Nanning to other cities in China?
If so, we can arrange group tour in Beijing, Xian, Guilin, Shanghai, but not students group tour.
If not, could you let me know more exactly your travel information?
1) When do you want to have a tour?
2) Where do you want to visit?
3) How many people will be in this tour?
4) Do you want to book hotel from us?
Feel free to contact with us in any moment by mail if you have any question on China tour service.
Have a nice day!
Best Regards
Peggy
