Yangzhou's west gate, also known as Tongsimen, can be traced back to the later weeks of the ancient five generations. When I came here, I stepped on every brick under my feet and felt full of a heavy sense of historical era. The whole museum is really not very big, a short 10 minutes may be able to walk, but it is really not enough to understand its historical changes within this 10 minutes. The museum staff also showed us a lot of cultural relics and written records.
