I'm jelous of you being able to take all with you! We've spent now about 3 and half weeks in China, but i was able to take only 18-55mm with me due limitations of bags (we're travelling with 20mnth old baby girl).
Post some shots when you're back, i'll do the same, even we didn't this time travel so much around. We were mostly in Guangdong province, around Dongguan where my wifes family lives.
Zhangjiajie and Huangshan are on my list to visit but not near the top at the moment
