What are the nearby tourist cities in Suzhou?

Hello: 1. Nanjing, Wuxi and Hangzhou are all famous tourist cities near Suzhou, just like Suzhou. If you can only use weekends, you can go to Wuxi or Shanghai to play; If you have 4-5 days, you can play together in Wuxi and Nanjing, or in Hangzhou and Shanghai. 2. Mudu, Tongli and Zhouzhuang, ancient towns in the south of the Yangtze River near Suzhou, and Lingyan Mountain near Taihu Lake, I wonder if you have gone? If you haven't been there, you might as well go to play first, and you can go back and forth on the same day.
