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.
I searched the ancient city wall of Yangzhou on the internet. Because it rained, I took a taxi, but I didn't think it was near our hotel. Nobody visited it. We looked at it in detail. The city wall is in the center of the city. It is not well protected and the venues are not big.
