Nope none of us spoke a shred of chinese and didn't really learn much by the time we had finished.
Getting around wasn't a problem, we usually got all the places we wanted to go to written on a piece of paper before we left, or looked it up on the internet and took a photo of it and showed it to the taxi driver, but then again, you won't have these fun problems.
We always had a handful of hotel cards each in case we got lose, just show a taxi driver the hotel card to return home
Younger people spoke reasonable english, but most people dont have a clue, although sign language goes a long way, as does a piece of paper and a pen.
Food wasnt a problem either, some places had english menus that were very non descriptive, so we used to order lots of food to make sure if any of it was bad, we wouldnt be hungry. We usually spent around a tenner on dinner,once we spent closer to £20 and we did order enough food to feed 6-7 people.
If they had no menu we would just look at what other people were eating.
