Known requirements take "Hexane + Ethyl Acetate + Polarity" as the core and direction, and create an ancient classical Chinese. The following examples show the thinking and discussion of the ancients in similar situations by describing the properties of two substances and the related content of polarity:

"On the Polarity of Two Liquids"

All liquids in the world have their own characteristics. Today there are two liquids, one hexane and one ethyl acetate. Hexane is clear in color and light in quality, sparse in nature and difficult to bond with others, flowing but not stagnant, floating on the water, like an uninhibited guest, walking alone in the rivers and lakes, its polarity is weak, and it is difficult to form a fettered state.

Ethyl acetate has a fragrant and fragrant taste, and the quality is also clear, but it is slightly more friendly than hexane. It is also in things, and can be compatible with several, like a sentient person, and is good at forming other things. Compared with the two, the difference in polarity is obvious. The non-polarity of hexane, if the hermit is far away, is alone; the polarity of ethyl acetate, like a person who has entered the world, is around.

View the mixing of the two, just like the meeting of yin and yang, affecting each other. The change in polarity is very subtle, and those who are not discerning cannot understand it. Or repel each other and divide, or attract and melt, all because of the polarity. The mystery of this, although not overnight, but with great dedication to explore, you will gain something, which can be used in various skills and benefits a lot.
