I took the chance to visit Shanghai since my sister is there for a short-term work assignment, and thus I have a place to stay. =) Of course I was glad to be seeing my sister again. I believe in the course of the last 2 years I have seen her twice including this time.
Shanghai is in general very crowded and has too much traffic. The air was hazy (not sure if its pollution) the whole time I was there, kinda disappointing since I can't enjoy the city lights at night. In a way, I felt more stressed than before the vacation. I need another vacation to get over this vacation.
