"...whilst visiting China" sticks in the craw a little. You get to be a local laowai for a while and after that you can hit the road, punk!
Nonetheless, 2 and 3 are probably timeless. But re 8, a kid did exactly that the other day while eating with his mother in a restaurant I frequent. The mother was bustling about the place, straightening stuff and looking over her shoulder. She saw a back door (and presumably a bathroom or sink back there), so hauled the kid off to wash hands. I looked over and gasped! TWO CHOPSTICKS STICKING UP IN A BOWL OF RICE! I had talismans though. The death curse passed me by and must have alighted on one of the many other students piling into the room, thank god.
