Life is an illusion. Many years later, when I walked slowly through the mottled city wall covered with moss and vines, I could faintly hear laughter and laughter inside the wall. Unconsciously, so much time has passed. It seemed like just overnight, then all the people in my memory collapsed like a house and left my life. Wave and smile at me from places that are just out of my reach. So, my dear, please carry a lamp on the road to the next life and see the desolation and prosperity of this world with me...
