I haven't used it here but with such a big Chinese community I am sure it works here like it does in China and HK.
I used it in China/HK and works a treat but a little hit and miss. As WL's is illegal in China this is one of the main ways to find the independent girls through the look around feature. Need to have some Mandarin there but here would be a different story.
Maybe I need to fire up my we chat here!
