it depends on which area you'd like to improve on ( :

for spoken, i do recommand one to one class that could correct your pronounciations and tones plus study what natives actually speak in a natural way, but for written Chinese, you'd better go to the school where there are heaps of homeworks and reading tasks.

As Jihai mentioned, having Chinese friends help a lot, and probably the best way ever to have the fastest progress in Spoken Chinese. I've improved my Chinese dramatically with this way within an year, and have no problem to communicate with Chinese people for various topics from politics&economic to daily life stuffs.

well, all the best for your study lol

ya, i went there as well. but, my favourite mexican bun doesn't look as delicious as before. ) : still, seems to be way better than before though.

i bought a bottle of fish sauce last year from Carrefour on Beijing road ( :

It was made in Thailand and the taste was alright actually.

it's called 鱼露(Yu Lu) in Chinese, costed me around RMB 10 for the
huge bottle. I saw the same one in the local market near by
my house yesterday. It shouldn't be a problem to find it ( :

ya, i felt that! i actually got out of my apt and just waited for a while.

saw lots of chinese people already had come out (：

i did it last year through travel agency in the city centre, HK.
