Where would you go if you were in China? Spring Festival is coming and I don't want to be stuck in my apartment for weeks.

Spring Festival sucks because everything closes, all your friends go out of the country and there's nothing to do. I can't leave the country or I'll invalidate my immigration paperwork. Where would you go if you were in China and had a couple of weeks? Not the usual Great Wall Terracotta warriors stuff, but the cool things people want to do but can't. Maybe Red tourism? That's a whole tourism category in China but it's made for domestic audiences and is usually boring. Few artifacts, just lots of dioramas and photostats of old newspaper articles. More educational for CPC cadres. I've got the nationwide highspeed rail network at my command and enough money to keep me for the holiday. It'll be crowded because everyone else is traveling too but it's better than being stuck in my apartment. No beaches or sun, it's winter and Sanya is overrun with Russians anyway.
