A very small museum, free of charge, can take children to see, understand the history of Yangzhou's ancient city wall, walk in the ruins of the fixed wall, then touch the ancient city wall, feel the feeling...
Before I came to Yangzhou, I didn't know that there were ancient city walls here. Only when I saw them, I knew that Yangzhou had a history, and it was a city wall of Song Dynasty, with a history of thousands of years. Although the museum is not big enough, it will be finished in a few minutes, but free is still good, you can also learn about history, it is worth recommending.
