The idiom comes from Lu Yao's Ordinary World, Volume III, Chapter 20: "Mountains don't turn into water. He is deeply rooted, and then everything else can be solved.
Mountains will not turn into water. In other words, mountains are fixed, while water is alive and flowing. This is a natural phenomenon and natural law. In fact, everything in the world is not static, let alone static, and is changing quietly.
Its stealth significance lies in warning the world. No matter who you are, no matter what you do, no matter what you say, you should leave room, you can't cover everything, you can't say too much, you should leave yourself room for manoeuvre and retreat. Two mountains can't get together, but there is always a chance for two people to meet, that is, bow their heads and see each other.
Although the world is big, people are alive and mobile, and they will meet one day, and they will meet one day. Even if we meet, we will still talk and laugh, and we will not be embarrassed.
It's a natural phenomenon that mountains don't turn into water, but there are many reasons to be a man here. A person's life is full of twists and turns. First of all, we must live the bottom line of being a man, that is, be honest and trustworthy, dare to take responsibility, and we will get results when we say it. Although the mountains don't turn, the water flows naturally, so does everything in the world. Problems and contradictions are fixed, but the people who solve them are flexible.
