Hong Kong and Nanjing subway systems are spectacular. I dont speak or read the language and never once did I get lost because there are super easy to understand signs _everywhere_ and usually an electronic map that indicates the station you just left and the one you're going to, above all the doors to the cars inside. Never once gotten lost, embarrassed i can't say the same for BART.
