I would like to ask what the following sentence means? What does it mean to make friends with each other based on benefits, and the benefits will be dispersed when all benefits are exhausted; only if we get along with each other with righteousness, we will achieve long-term success. What does it mean? Thanks.

1. Interpretation: Communicate for the purpose of benefit. Without benefit, communication will break up. If you use strength to communicate, if your strength is gone, the relationship will collapse. Use your rights to communicate. If your rights are gone, such interactions will be meaningless. Communicate based on feelings. If the feelings are cut off, the friendship will be hurt. Only relationships with heart can last long. 2. From: "Wen Zhongzi: Rites and Music" and "Zhongshuo: Rites and Music" by Wang Tong of the Sui Dynasty (also known as Zhongyan, also known as Wen Zhongzi) 3. It mainly tells us: No matter what the matter is, only the sincerity is the most sincere at this time. The longest lasting.
