Communication is the most urgent and difficult thing for human being. Except for survival, people cope with all spiritual problems such as loneliness and fear with communication.

When we are young, we cry for food and shout when we are fear; during adolescent, we hurry to say love, with little technic. 

People assume with their growth, the problem of communication can be solved through enhanced technic. But oppositely, the more we try to improve the accuracy of expression, the more we are away from our original purpose; the more we master the degree of our expression, the more we doubt the sincerity of our expression, meanwhile, douting others.
