After golf, we went to Qing Hue Fong (清河坊). It is a pedestrian street with ancient architecture, building like in Sung Dynasty. Hangzhou was the center of producing medicine in the old days. There were a lot of different brands and they had their own medicine plant here. Nowadays most of them were converted into museums.
I believe the city still has many medicine firms nowadays. I was told by a guy who invested in a few of the largest medicine companies in Hangzhou.
