Remember the matter of Hakdi
In the past, there was a wise man named Hakdi, who specialized in the art of chemical engineering. His talents are smart and wise, and he has great ambitions. He wants to use what he has learned to benefit the world.

Hakdi studies the principles of chemical engineering and explores the wonders of material changes. In the mechanism of reaction, he analyzes it in detail; in the design of the process, he is ingenious. Often in the room, he observes the decomposition of various substances, observes the change of their shape, and studies the mystery of yin and yang.

He is also a human being, and he is diligent. He studies day and night, and never stops working. Every problem must be traced back to the source, and the solution must be found. His friend may have persuaded him to take a break, and Hakdi said: "The science of chemical industry is extensive and profound, and it is related to the prosperity of people's livelihood. Dare to slack off?"

And Hakdi is good at making friends with people and is willing to share what he has learned. If you are confused, you will teach each other your money. With what you know, you will inspire wisdom. Everyone respects him and respects him as a leader in chemical industry.

Hakdi uses the way of chemical industry to benefit the world. The method he created, or makes the product rich, or makes the craftsmanship lean, benefits the four sides. Although he has worked hard, he is happy with it, and he will use it to contribute to the society and get what he wants. Later scholars should take Hakdi as an example, study diligently, and use the energy of chemical industry to benefit the family and country.
