This is a motto of Zhang Boling, the founder and famous educator of Nankai academic system. Its essence lies in its connection with "good people" and the possibility of becoming a "gentleman"; If you get along with "villains", you may "flow into villains". Being is actually a "warning of making friends"-what kind of people you should choose to get along with.

In my opinion, this kind of discourse thought is "resistant to reading", but it should be done with dialectical thinking in particular.

What is the goodness of a "good man"? What is the "evil" of the "wicked" and where is it? This must be clear first. Otherwise, such words and ideas cannot be put into practice.

When people reach "goodness", their "truth" and "beauty" also exist. To be realistic, who doesn't want to associate and get along with people who are "true, kind and beautiful"? The life I have experienced really tells me that this is not necessarily the case. Why? For one reason, there are people in life who can't really recognize the truth, goodness and beauty-they seriously lack the education and ability of the truth, goodness and beauty. Without the ability of "truth, goodness and beauty", how can we communicate and get along with people who are "truth, goodness and beauty"? The further reason is the lack of education and ability of "truth, goodness and beauty". Don't people who associate with "truth, goodness and beauty" feel oppressed? Not "losing face"? Even the "right to speak" has been lost?

Therefore, "getting along with good people is a gentleman" needs to be treated as "divided into two", which is not a complete inevitable achievement. It can be said with certainty that if people's "kindness" education is not sufficient, they will form the orientation of "unwilling to get along with good people", and it is impossible for "good people" to "get their hands on" others and become gentlemen. I think this is the deepest and truest place in real life.

"Get along with the wicked" should be a kind of "birds of a feather flock together, and people are divided into groups". Life practice tells me, or what I have experienced tells me that even if the "good guy" and the "evil guy" get along for a long time, they are more discriminating and can't "dye" each other-in essence, the "good guy" will never degenerate into the "evil guy" unless the essence is the return of "evil".

As above, it is a reflection on Mr. Zhang Boling's proverbs. The more you think about it, the more you understand the significance and importance of choosing in life communication, especially when the true colors of "good" and "evil" are not fully presented.

"Lu Yao knows horsepower and sees people's hearts for a long time." This should be a value measure and help to "get along with good people".
