The following is an ancient classical Chinese written with "Sodium And Fluorine Formula" (the chemical formula of sodium and fluorine) as the core:

Between heaven and earth, yin and yang sympathize, and all things metamorphose. There are two things, one is sodium, which is strong in nature, and often shows a positive state in various reactions; the other is fluoride, which is also active in nature and has the ability to strong devour.

Sodium is light in weight and silver-white in color, and it boils sharply in contact with water. It is like a dragon rising in the abyss, sounding in the four fields, escaping hydrogen and turning alkali, and its change is fast and intense. Fluoride, the yellow-green of qi, also taste and strong in nature, can combine with various things, and there is no one who is unyielding.

When sodium and fluoride meet, yin and yang are combined, and then a new substance is formed. Sodium loses one of its positive electrons, and fluoride obtains it. The two are connected by an ion bond, forming the shape of sodium fluoride. Its chemical formula is NaF. This compound is more stable than sodium and fluoride. It can be used for various matters, or to help medicine, or to work, and it can show its work.

Looking at the combination of sodium and fluoride, we can see that all things in heaven and earth, although they have their own properties, when they meet, they can form each other and form new substances. This wonder of creation cannot be tested by human beings.
