The friendship between gentlemen is as light as water, which means that the communication between gentlemen is as plain as water, not for fame and wealth, not for vanity. "Zhuangzi Samwood": "And the friendship between gentlemen is as light as water, and the friendship between villains is as sweet as ever; A gentleman is indifferent to his relatives, and a villain is willing to give up. "

Because the friendship between gentlemen is as clear and insipid as water, we can have a long-term relationship. Don't get me wrong!

Because gentlemen have noble sentiments, their friendship is as light as water. The "indifferent" here does not mean that the feelings between gentlemen are as light as water, but that the interaction between gentlemen does not contain any utilitarian heart. Their interaction is purely friendship, but it is long-term and cordial.
