about trust Trust is a thing that intangible and yet extremely important for almost everyone. In today's society, no one is an isolated island, everyone needs others to survive and sustain his or her own life. It is trust on which we build up our social relationship with others. Therefore, we need to trust others, hoping they could fulfill our expectations, and vise versa. At the same time, we want to be trust worthy, which is not only the basis of realizing self-value, but also a way to satisfy one's inner needs of being needed. And, in certain cases, we can't trust the other party completely, so we need to sign a contract to bind two parties with every obligation and right clearly stated in it in details. With the help of contract and law, we can also build up trust.
