Hi...how to go to Hunan Province from Beijing ??? train n air ???

Well, it's a major province in China. And it contains many cities. Which one do you want to go?
Is it Changsha, the provincial capital?
If yes, take high-speed train from Beijing West Railway Station, get off at Changsha South Railway Station. It takes 6 to 8 hours on the way. The schedules are from 06:03 to 15:40. The ticket fare of first class seat is CNY1038 and second class seat is CNY649. Or you can search the real time schedule on your own on this website.

If by air, it takes about 2.5 hours. and the fare is from CNY500 to CNY1200 due to different discounts.

O yea...
Thank you darling :)
