I'll be in HK on 30th Jan, get my visa, then hit Shenzen start of Feb.
I'm an overseas Chinese, so I speak Canto and Mandarin and so can pass off as local. Any China newbies want to go hunting together, especially in the night, so it's safer and just to hang out in maybe some off the track places. I'm not familiar with SZ but would like to explore more than just touristy places.
PM me and let me know.
