"The stream falls with old scars and withered wild ports, and the tortoise shell screen is intoxicating" to describe the tortoise. Because this sentence describes the habitat environment and the characteristics of the tortoise shell, in which "old mark" represents the path of tortoise crawling, "dry wild harbor" depicts the picture of tortoise moving in a dry place, and "tortoise shell screen" directly depicts the tortoise shell. And "Zuiyan Valley" may describe the turtle's eyes, which are as blurred as drunk.
