Hangzhou and Shanghai in December

For HZ, if you just have a one day trip, West Lake is the must-seeing place and if you want to enjoy the beauty of the lake, you need one day.
For Shanghai, the Bund, Nanjing Road, Yuyuan Garden, Jade Buddha Temple, Shanghai Museum and Zhujiajiao Water Town are highly recommended. After visiting all these places, you can go to Shanghai Museum, World Financial Center, World Financial Center and Xin Tian Di if you have extra time.
