Are you looking for streets in China? Do you need directions? Which bus should you take? Which underground line do you need in Beijing, or Shanghai? How long will it take to get from A to B?
Mapbar.com has an answer to every single question.

mapbar.com is simply the best and most useful website I have ever come across in China. It's awesome.

The only drawback being that it's in Chinese. That's no biggy however. Just enter the pinyin of the place you are (a) and the place you want to go to (b) and BOOM!

Out of 10? 11!
