Walking on the ancient road, looking at the deep ruts on both sides, lamenting the wonderful dialogue of time and space. I strolled through the ancient street, stepped on the historical slabs, felt the footprints of the ancestors, every step was a vision of history. The road under my feet, six hundred years ago, some people also stepped foot, what kind of mood did they then? Those old gray brick houses, ancient city walls, as if talking about the glory and loneliness.
