When the forest runs out of water, you will get a mountain with a small mouth, as if there were light. Leave the boat and enter from the mouth. Only when you are very narrow at first can you understand people. After a few steps, you will be suddenly enlightened. The land is flat and spacious, and the houses are just like it. There are fertile fields, beautiful ponds, mulberry and bamboo. Traffic in buildings, chickens and dogs hear each other. Among them, men and women dress like strangers. Yellow hair droops and enjoys itself.
