The river boy is just a legend. Originated in the upper reaches of the Yellow River Basin in China. Legend has it that it is 60 cm to 1 m high in Japan, with an ape-like figure, hands and feet like ducks or toads, a turtle shell on its back, a beak, hair on its head and a dome on its top. If there is water, you will die; if there is no water, you will die. Have special abilities. Legend has it that people with bad conduct will dive into the water and eat their own internal organs. Although it is only a legend, I still feel that there is no absolute good or bad! In Summer of the River Boy, he used the river boy to reflect the problems of human beings and the environment. In contrast, the most terrible thing is people!
