2. It takes about 13k m to get from Wukesong to Huguo Temple, and it takes about 40 minutes. It is suggested to eat snacks at Huguo Temple, and then go to Gongwangfu-Old Beijing Hutong-Guo Moruo's former residence-Bar Street (partly because some of them can only walk)-Yindingqiao-Gulou East Street-Nanluoguxiang North Exit.
I suggest you check the Shichahai website before you come, the information on it is relatively complete. In addition, you can go to the Beijing Tourist Information Office on the east side of Little Square in Qianhai to get a map.
