I'll admit I hadn't heard of Hangzhou before I went, and it ended up becoming one of my favorite places I visited in China. The lake is peaceful and beautiful, the culture and history fascinating, and it's an easy day trip from nearby Shanghai. Worth it even if you can't swing an overnight stay.
I feel it is a little bit overrated. Although the lake was very beautiful, it was maybe the only place that was special. I feel there are better places to go to in China.
What a beautiful and interesting place in Hangzhou. The popular places are Qiantangjiang ,Xihu and many bridges.
Beautiful sightseeing! Amazing Lake views. And awesome show at night: don't miss it!
