How to understand the word "Li" interlaced like a mountain, and interlaced like a mountain?

From "interlacing like a mountain" to "interlacing like a mountain", it embodies the universal connection of things, which is not only a promotion and leap in understanding, but also the only way to expand ideas and creatively carry out work. The word "reason" shows that people should be good at jumping out of their own industries, fields and majors, making inferences from others, understanding the universal connection of things at a higher level, learning from the experience of different industries, fields and majors, enriching themselves, broadening their horizons, opening up their ideas, getting rid of limitations, grasping the regularity and realizing creativity. Practice tells us that the so-called "layman" and "expert" are only relative.
