On Horned Galls The Essentials of Chemical Engineering
In ancient times, there were aliens who lived in the mountains and forests, and often observed the changes of plants, insects and insects. One day, I saw the horned gall on the wood, its shape was strange and its color was mottled. Strange to strangers, I can't stop studying it carefully.

At that time, in the Horned Gall Chemical Engineering Links, everyone was ignorant. However, strangers observe the horned gall, think about it, and understand the wonders of creation, or have the principles of chemical engineering.

Horned galls are born in wood, and must be sympathetic to foreign objects because of the wood. The quality of wood is nourished by water and soil, and it is moistened by qi. And the horned gall is unique, and the cover has a special transformation. The formation of the horn gall is caused by the abnormal transportation and transformation of the body fluid of the wood, and it gathers to form a gall. In this process, it is just like the change of the chemical industry, the fusion of substances, and the deformation of the state is easy.

Extrapolating from the chemical industry, all the chemical combination must also follow the rules. The formation of the horn gall has its own reasons, and the combination of the chemical industry is unruly. The compatibility of raw materials, the proportion is accurate, just like the wood is suitable for water and earth; the reaction conditions are moderate, warm and cool, similar to the situation encountered when the horn gall is born.

And the shape and quality of the horn gall can be used as a lesson for the chemical industry. Its firmness, color and texture are all caused by changes from the inside out. Chemical products should also seek their pure quality and beauty, suitable for their use.

Inhumans use horned galls as a guide to explore the mystery of chemical industry. Although the mountains and forests are remote and have not been discussed in detail in ancient books, they still use the image of nature to deduce, and gradually understand the way of chemical industry. Future generations should follow this ambition and take nature as a teacher to understand the subtlety of chemical industry, which can be used in the world and benefit all people.
