A Tale of Two Shanghais

> In Shanghai, the Huangpu River divides old and new.

Pudong is new, but Puxi is not "the old one". It is mixed with old historical sites and modern buildings. It lives with its history, and it grows actively. It doesn't have to destroy all the old stuff, but it also doesn't have to slow down its pace for them. I believe it is the same for any city (e.g. in Europe) with history.
