I'm planning on going to China in mid-November and I'm nervous about the weather. I was going to travel around China for a month or so, starting from Beijing and working my way south. I'm worried that by the time it gets to December, the weather is going to be less than ideal for travelling.

Any suggestions or reassurance? Places to avoid that are particularly cold?

Am I just being a wuss?

And on another wussy note--I'm going to be travelling alone, but I've heard that China in the winter can be less than inviting for solo travellers. Tell me it's not so.

Also, what do you think of travelling around China by train vs planes? Flights look very cheap, but not sure which is better.
