The mouth is the only one of the body's five sense organs that has multiple functions. The eyes see. The ears hear. But the mouth not only chews and tastes food, it also speaks, sings, smiles, and kisses, expressing our feelings and passing on ideas.
人體五官中，眼只負責看、耳只主管聽，唯獨「口」具備多功能，既可說話、唱歌，又負責飲食咀嚼，還能以微笑、親吻來傳情達意。
