Classic quote from the ordinary world: A person's desires cannot all be reasonable. If one desire is unreasonable, it will force another desire to be unreasonable. Everything in the world is limited, but human desires are like an endless source that will never be exhausted. Once the three of them lost control, they would hurt others like wild beasts. In this world, there is nothing more destructive than human desire. There is nothing more reliable than honesty in this world. The desire of a person is terrible. It can turn a person into a devil or an angel. In this world, true happiness can only be obtained through labor. The desires of eight people are varied, but reasonable desires will make people better. The desire of a human being is selfish. It will only think for itself and not for others. Desires are hard to control, but they can also make people stronger.
