Three famous sayings: "A light promise will lead to a lack of words", "A broken promise will not stand", and "A small trust will make a big trust stand" are all related to integrity.

"A light promise will lead to a lack of words" comes from Chapter 63 of "Laozi", which means that a promise made easily must lack credibility.

"Broken trust cannot establish", from "Zuo Zhuan. The Twenty-Two Years of Duke Xiang", which means that people who do not keep their trust cannot gain a foothold in society. It is extended to the inability to gain a foothold in society and the inability to gain recognition from others.

“When small faith is established, great faith is established.” This comes from "Han Feizi·Wai Chu Shuo, Upper Left Chapter", which means that only when small integrity is established, great integrity can be established.

Extended information:

The sentence "A light promise will lead to a lack of faith" is very philosophical. The previous sentence "A light promise will lead to a lack of faith" is easier to understand. It means making a promise easily. The promise must lack credibility. The latter sentence "what is easy must be difficult" is a bit difficult to understand literally. Combined with Lao Tzu's context at that time, we know that this sentence means that if you think or describe something as easy, you can actually do it. There will be more trouble.

The first half of the sentence educates us not to make promises easily. As long as we make a promise, we must fulfill it seriously and not lose our faith. The second half of the sentence educates us not to underestimate the things or opponents we encounter, otherwise we will definitely Will fail due to lack of stamina and necessary preparation in the process of doing this.
