What is a stubborn thing?

"Yao" is an ancient symbol of image number, which is widely used in Zhouyi. It has both the meaning of "line" and the symbolic meaning of "yin and yang". In Zhouyi, "hexagram" is a symbol composed of three horizontal lines or three vertical lines, which is used to indicate yin or yang in a hexagram.

In Zhouyi, "Yao" is a symbol, which is used to express the relationship between Yin and Yang. Yin is a horizontal line and Yang is a vertical line. On each hexagram, we can read a "change of heart". These hexagrams are called "hexagrams". These poems speculate and explain the development and changes of things according to the yin and yang attributes and the four images (too little, supreme and moral).

"Yao" is a very important symbol in ancient image mathematics, which represents people's knowledge and understanding of the whole universe. This kind of understanding is not based on direct observation and perception of the physical world, but on mathematical symbols, through reasoning and analogy to understand the world. This idea of image mathematics has also become an important part of China's ancient philosophy.

In the modern context, the word "stubbornness" can also be understood as some kind of "divination". In traditional culture, people often rely on divination or fortune telling to speculate on the development trend of things. These methods of divination and fortune telling basically use the concept and method of "Yi". This method first needs to determine the yin and yang and the four images of things, and then calculate and predict the development and changes of things through the change of ideas.

"Gua" is a very important concept and method in both ancient image numbers and modern divination. It represents not only a symbol, but also a way to know the world and understand the universe. This way is not only the embodiment of scientific thinking, but also the embodiment of philosophical thinking.
