The cognitive law that man cognizes things from the near to the far, from entity to non-entity, from the simple to the complex, and from the concrete to the abstract determines the basic role of body parts in cognizing the world. And the metaphorization of body-part terms is one of the basic means of forming and expressing concepts.
