How to interpret the Book of Changes?

In the fifty-third hexagram of the Book of Changes, the wind and mountains gradually spread, and the clouds went up and down.

"Shuo Gua" says "Gen is a mountain", that is, Gen Gua looks like a mountain. What is a mountain? "Zhou Yu" said: "Mountains and soil meet."

It is more accurate to add a word "stone" after the word "earth". Modern Chinese Dictionary defines "mountain" as "a towering part formed by the ground." Shao Yong, a great master of Yi Studies in the Northern Song Dynasty, defined "mountain" as: "A mountain is also a mountain where (Yang) is attached to the yin and stops moving." The divination shape of root divination is one yang pressing one yin, which is exactly the case. Taking the early morning sun and the shadow of the mountain as images, it can also be intuitively proved that divination is like a mountain.

Mr. Tang Junyi, one of the representatives of modern Neo-Confucianism, said: "Yin and Yang originally only refer to the back-to-back relationship with sunshine, so it is a quite daily phenomenon, and later it was changed to refer to the nature of various relationships." So, what is the relationship between mountains and sunshine? Everyone knows that the south of the mountain is yang and the north of the mountain is yin. When I was a child, I read: "Get up in the morning and face the sun. The front is east and the back is west; The left is north and the right is south. " We rotate the divinatory form of Gen Gua 90 degrees to the right, and it becomes the shape of left yin, middle yin and right yang. The north on the left is cloudy, the south on the right is sunny, and the middle is also cloudy, belonging to the mountain. The divinatory symbols shaped like mountains may enlighten us to understand the so-called "roller coaster" market in the securities market. Whether this connection is reasonable or not needs your careful observation and confirmation.
