The Knocker and the Dragon

Everyone seems to live in an isolated city. The city is separated from the outside world by mountains and rivers, and words and touch are the only ways to enter the city. However, this road is also extremely bumpy. I traveled across mountains and rivers just to come to your city. If you are hospitable, please wave the welcome flag on the city tower. If you have no mercy for me, please don't tell me that my journey was in vain. If you are as lonely as me, then accompany me on the road. We will light the swaying beacon smoke; we will ride on the unruly horse; I will witness a golden age with you; I will tell you: "I am here"... I firmly believe that one day we will knock on all city doors.
