I want to travel by myself, but I don't want to go to Suzhou, Shanghai, Hangzhou and Wuzhen with a group.

You can go all the way south, Zhengzhou-Suzhou-Shanghai-Wuzhen-Hangzhou-Zhengzhou. You can travel by train, except that the high-speed train from Shanghai to Wuzhen can only be Tongxiang, and take bus No.282 to Wuzhen. From Wuzhen to Hangzhou, it is recommended to take a bus, which is quite convenient and there are many flights. Wuzhen recommends a two-day and one-night tour, staying at B&B in Tashi for one night to watch the night scene, and going to the Wubaihui Bar near Shuangqiao to watch a performance and experience the nightlife of the ancient town.
