你好!
I am a current Australian university student, and I have (somehow) made it to the second round of the "Hanyu Bridge" Chinese Proficiency Competition which will be held in Changsha, China.
We will be arriving in China in July, and I was just wondering what to expect. I have never been to Hunan, and I've got a few questions:
1) If I bring a laptop, is wireless internet easily available?
2) I have heard several rumors that "Facebook" is banned. Is this true?
3) I do know it'll be summer when I get there but does it get cold at night?
4) If anyone has heard of this competition, could you please tell me more about it? I can't read the official website as it is completely in Mandarin!
5) Finally, the most important question: I would LOVE to learn some Xiang Chinese/ Chang Sha hua, but the internet doesn't seem to have much...is there anyone out there who can give me a hand?
Thank you for any help you can provide! =)
Cheers,
Rach
