3. Ewenki people have the custom of forbidding to have a haircut and shave in the afternoon. They are worried that having a haircut and shaving in the afternoon will change their appearance and their souls will not return to their bodies smoothly. Don't have a haircut or shave when you are hungry. There is a folk saying that "you don't take a bath when you are full, and you don't shave when you are hungry". This is also worrying about the safety of "body" and "soul".
