Sanjay, I am not very familiar with the "reef Scene" in Shanghai. I believe there is a public aquarium there.
I spent 3 years in Suzhou which is about 2 hours from Shanghai. At that time I was not keeping any tanks.
I am now in Tianjin which is just outside of Beijing and just discovering eveything here.
My initial contacts in this area have been limited and the tanks I first discovered were as I described in an earlier post here.
Now I am starting to find that methods and techniques are quite similar to what we "know" in the USA. I have seen a few very elaborate setups that included UV sterilizer, skimmers, calcium reactors and ultimate lighting such as MH and PC's.
However the majority of reef setups still fall within what we consider to be fish only setups. In all fairness, the tanks that I have seen have been very well taken care of and the livestock appears to be thriving even with minimal setups.
I was VERY surprised when my Local Chinese Fish guy told me water changes are evry 5 months 50% change.
Anyway, it's an interesting experience.
