This lot means "言之成理". It is an admonition to the parties involved not to be too subjective. A person with a good understanding of reason and a keen sense of observation can often foresee the future and tell how things will turn out, but there is a difference between being confident and being complacent. When one becomes too subjective, one becomes complacent and conceited without realizing it, and is unable to accept different opinions and criticisms. There are no absolutes, and people's ideas are constantly changing. Therefore, we should be careful not to make snap judgments based solely on personal positions and feelings, but to maintain a humble and prudent attitude, and to always approach matters objectively and inclusively.
