Why are the four divinatory symbols in the Book of Changes all divinatory symbols with water?

The four divinatory symbols are all divinatory symbols with water, that is to say, the names of these four divinatory symbols all have the word with water, and the water phase is used as a symbol to explain the divinatory symbols. The word "water" means drowning and is destroyed by water, which mainly represents the image of evil. Therefore, these four hexagrams are the most difficult hexagrams in Zhouyi. They are the third divination in Zhouyi-Shuileitun divination, the twenty-ninth divination-Kanyu Shuigua, the thirty-ninth divination-Shuishan divination and the forty-seventh divination-Zeshui Kungua. You can tell by the name. The four difficult hexagrams are called Kan, Tun, Kun for short.

According to the water image, Kangua, one of the four difficult hexagrams, is a kind of difficulties and obstacles, and it is full of dangers, which means that what it encounters is ups and downs and is at a low ebb, which requires people to work hard and forge ahead.

The thunder participating in divination means that the thunder is loud, the dry thunder does not rain, and the rain is still above the clouds, expressing the desire for rain, but it can also be understood as timely rain in the heart or things. So it looks dangerous and in a dilemma.

Take Ze as an example. What is most needed in Ze Lake is water. If there is no water in Zehu Lake, it is conceivable, just like a person can't live without blood in his body. It's just that people here have no external material support, such as human, financial and material resources, which leads to poverty and weak will to live.

Divination uses the description of mountains and rivers to illustrate divination. If there is still running water on the mountain, it seems to be peaceful. In fact, if a person climbs a mountain and meets the water flowing downstream, he can see the danger at that time, which shows that he is in a dilemma and hinders the danger.

As can be seen from the four hexagrams, they are all based on water, which indicates countless obstacles in life. Describe various dilemmas. In fact, no matter what numbers and events, they all test our attitude, methods, wisdom and reaction to solving difficulties.
