I have been to South East China twice before with friends who have relatives from there. I would like to see more. I want to travel around the south part of the county by train (soft sleeper) for two months or so in the months of December/January/February when it's not so hot. My question is, are rail passes available like in other countries? Also, I don't want a tour or guide, just an interpreter. I know where I want to go and see. Any suggestions?

Thanks in advance-
Gene
