Here some impressions from Shanghai. It is not my favorite city in China but you can get here nearly everything. Shanghai is also one of the most expensive cities in southeast Asia. I stayed in Xuhui District (徐汇区). The highest skyscraper are in Pudong District (浦东区). You also can go to the top of one of them. For 180 元 you can go to the floors 94, 97 and 100.
