Silence means no sound. But in fact, there is no  thing as true silence for a living being, because silence    is an exposure of the mind and the heart.
Some people use silence as a disguise(伪装) of the (empty) of the head. Some use it as  means to describe their puzzlement and sadness. And some use it as a way of  (express) their angers.
What do silent people say? They say that “silence is golden”, but  is the nature of this “gold”? It can include honesty and kindness; it can stand for separation  fame and fortune;    it can also act as an excuse for untruthfulness and cunning.
Is it true that permanent silence (represent) by death?
Perhaps even death cannot represent true silence, for the carrier of the soul can turn into dust, so that the sincere and wise voices are from the bottom of the heart will cause long-lasting echoes in the seas of human hearts.
