I went to Hangzhou last month. It was awesome. I went to Zhejiang university. Here's the picture of me standing in front of one of the building.
And here's a picture in front of a Line Store.
The Airbnb we stayed in was also cool. There was a PS4 in it for us to play.
My favourite was a bookshop. The environment was special and great. Here's it.
Wish you will have happy journey in Hangzhou.!
