Need help! Best university for Chinese language in Shanghai...

I've been living in China (Chongqing) for almost a year now, but have had no tuition so consider myself a newbie. I'm going back to the UK soon but want to come back out to live in Shanghai to study Chinese. I have been looking at Tongji University International School JBC Centre. Could anybody help me out and either reinforce my current option or suggest a better university. By the way, I only want the course to last for a maximum of one year (then I will go home). Thanks for your help...
