The Greatest Trust Is Not Found in Pledges.
最高的诚信，不限于誓约。中国古人认为，人言即“信”，诚信是人之为人的固有规定。“信”是盟约、誓言的内在精神；“约”只是“信”的一种表现形式。没有“信”，“约”不过是一纸空文；有了“信”，“约”才具有实际意义。它强调的是诚信精神。
The greatest trust includes but is not limited to pledges. Ancient Chinese believed that trust is a person standing by their word. To act in good faith is a basic requirement for a person to become fully human. Trust is essential for an agreement or a pledge. An agreement is only a representation of trust. Without trust, an agreement is just a piece of paper. An agreement is meaningful only when parties concerned have trust. This concept stresses the importance of the spirit of good faith.

（有很高德行的人，不限于担任一种官职；普遍的道理，不只适用于一件事物；最高的诚信，不限于誓约；天的四季变化，也无须整齐划一。）
Great virtue in a person does not come just from their official status. The application of a universal principle is not restricted to a single circumstance. The greatest trust does not necessarily need pledges. Changes in seasons need not follow a uniform pattern. (The Book of Rites)
