You need to be no Sherlock Homes to notice that Shanghai lacks in terms of green areas. Having said that, however, it's not until you see the city from above that you realise what an urban jungle this place really is!? (Anyone don't believe me? I recommend u to visit the City Planning Museum on People's Square). Geeeez... give this city some more parks and trees?!
Oh and btw.. Huangpu river is NOT that blue! Actually, it's not blue at all!
