Where can college students travel alone? What experiences can you share?

I think college students can go to Jiangsu or Zhejiang for poor travel, because the local tourism resources are very rich, and there are many free scenic spots, such as the famous West Lake, which are free. In the evening, they can also go to the West Lake to see the music fountain, so I think we can go to Jiangsu or Zhejiang, which I chose when I first went. Moreover, the traffic between Jiangsu and Zhejiang is very developed, and it is convenient to go to other cities.
