The main purpose of "Tiangong Kaiwu" is to show the rich and advanced wisdom and production methods of creation at that time through detailed records of various production technologies and crafts. The following is an ancient text created in a style similar to its connotation:

Between heaven and earth, all things are born, and people use ingenious thinking to make tools and control things. The skills of the craftsman are wonderful in combination with nature, and they study physics to become all kinds of treasures.

Watching the art of gold craftsmanship, mining the concentrates of mountains and rivers, calcined by fire, and tempered by thousands of times, it becomes a sharp blade and a strong tool. At the beginning, the ore is pure, hidden in the mountains, and people explore it with wisdom. Then it melts in the flood furnace, the tongue of fire licks, and the golden juice flows, like the blood of the earth. The craftsman holds the hammer with precision and power, and every blow gives the object the shape and spirit, or the sharpness of the sword, or the thickness of the kettle.

As for the earthwork, take the clay as the blank, shape it with the mind, and burn it through the kiln fire, and then it becomes the genus of pottery. The clay is soft and amorphous, and the craftsman kneads it, pinches it according to its nature, and gives it a round state. The fire in the kiln is like the work of creation, which transforms the body into a new body, hard and durable. It can be used as the roof of the house, and it can be used as the capacity of the utensil. It can shelter people and store things. There are many functions.

The wonderful thing about woodworking is to choose good wood and good materials, and use sawing, planing, chiseling and other tools to carve into tools The texture of wood is naturally interesting, and the craftsman follows the trend, either as a table and chair, or as a pillar. Its fine ones are joined with mortise and tenon, tightly sewn, and do not borrow nails and riveting, but they are very strong.

All kinds of skills rely on the strength of the craftsman's heart, and use natural things to create the benefits of the world. Those who are not diligent and eager to learn and study hard cannot come to it. The things they make are either for the needs of people's livelihood, or for the treasures of the world. They are all a combination of manpower and heaven's work, shining between heaven and earth.
