What are the main uses of this product? "Tiangong Kaiwu" is an ancient scientific and technological book in our country, and the following is answered in classical Chinese form.
To observe all kinds of products in the world, there are different uses. Today, this product is quite widely used. First, it can be used for the needs of people's livelihood. Between the daily use of the people, it adds convenience and comfort to life. For example, when you are at home, it can assist in cooking, making cooking more convenient and efficient; or it can be used for sorting and storage, so that the residence is orderly, the sundries have their place, and the home is clean and pleasant.
Second, it is also important in the way of labor and production. Craftsmen work, using this product as an auxiliary tool, can get twice the result with half the effort. For example, in the woodworking industry, this product can be used for accurate measurement, so that the size of the wood made is appropriate and the seam is tight; or it can help in the cutting and polishing process, so that the surface of the wood is smooth and the craftsmanship is exquisite. During farming, it can also be used as a part of the farming tool to assist in farming, sowing, harvesting and other agricultural tasks, improve the efficiency of farming, ensure that the grain is abundant, and the people have no worries about food and clothing.
Third, in the road of commercial trade, this product is also an important thing. Because of its wide range of uses and great demand, it can be circulated between shops and become a commodity traded by merchants. Merchants from the north and south sell them to various places, exchanging what they have and what they have, promoting economic prosperity, enabling the exchange of materials between the four sides, and the people can use what they need. The commerce in various places is also very active because of this.
Fourth, in terms of cultural inheritance and the dissemination of skills, this product also plays a role that cannot be ignored. With this product, craftsmen pass on their exquisite skills from generation to generation. The utensils they make carry the wisdom and skills of their ancestors and become the carrier of cultural inheritance. Later generations can see and use it to understand the ingenuity of the ancients, continue the cultural context, and keep traditional skills from being lost and passed on forever.

Looking at today's city, the competitive trend of this product is like the ancient battlefield competing for dominance. The main point of its competition is quality. Gu Yun: "If you want to be good at your work, you must first sharpen your tools." Today's products, if the quality is not refined, are like the disadvantage of the sword. Although there are ingenious skills, it is difficult to defeat the enemy. It is necessary to devote all your efforts to the improvement of quality, so that the materials are exquisite and the craftsmanship is exquisite, so that you can be invincible.
The next time is new. "If you are poor, you will change, and if you change, you will be able to work well, and the general situation will last for a long time." The market conditions change. If the product is conservative, it will be abandoned by the city. When seeking innovation and seeking differences, gaining insight into the changes in the world, introducing new skills, and creating new methods, so that the product is always new, like the water of a
Furthermore, the reputation. "People can't stand without trust, and the industry can't thrive without trust." The reputation of a product is like the virtue of a person. If you have a good reputation, you will respect it, and if you have a high reputation, you will be respected by the customers. When you keep your integrity and fulfill your promises, so that the reputation of the product is full of the city, and it is passed down from word to word. Like the spring breeze and rain, moisturizing things silently, the city's share can be gradually expanded.
It is also at the price. "The transactions in the city, those who benefit will follow them." If the price is too high, people will be discouraged; if the price is too low, although it can attract customers, it will be difficult for the profit to be thin for a long time. When the supply and demand of the city, weigh the cost, and seek a moderate price, so that customers feel the value for money, it is also profitable.
And in the publicity. "Good wine is also afraid of the deep alley." Although there are good products, if the publicity is not strong, it will be like a pearl in the dust. When you make good use of all kinds of publicity and publicize it widely, so that the name of the product will spread in the four directions. If the fire sends the letter, it will be heard from far and near, and the competition of the city will be better than the other.
These numbers complement each other and are all related to the competitiveness of the product in the city. Like the armies in the battle, the lack of one is weak. Only by making overall plans and making good use of its methods can we win the favor of the city and stand out in the competition.

Looking at this product, the simplicity of its production process is related to many factors. "Tiangong Kaiwu" has a saying: "The silk, linen, fur and brown in the world are all of quality, and the special face and color are still there. I don't believe it if I say that the creation is not laborious." When it comes to craftsmanship, the completion of all things depends on fine work.
Now when it comes to this product, if its material is rare, the process must also be exquisite. For example, in the industry of porcelain making, soil selection, mud practice, billet drawing, billet drying, engraving, glazing, kiln burning, all kinds of processes are interconnected and indispensable. Every step requires the exquisite skills of craftsmen, and a slight mistake will cause defects. If the material of this product is ordinary, but it seeks unique shape and excellent quality, the craftsmanship is also difficult to simplify.
Taking textiles as an example, there are many processes in the process of self-picking cotton, bouncing flowers, spinning threads, dyeing, and weaving ready-to-wear. If you want to weave fine fabrics with exquisite patterns and bright colors, there are strict requirements for the fineness of the spinning thread, the precision of dyeing, and the tightness of the weaving.
Contingent products have complex designs and need to integrate a variety of skills, such as ancient cloisonne, which integrates tire making, filigree, welding, dot blue, burnt blue, polishing, and gold plating. Craftsmen must be proficient in various techniques in order to create exquisite tools.
Therefore, when it comes to the production process of this product, it is difficult to generalize its simplicity. Anyone who wants to make a good product, regardless of the quality of the material or the simplicity of the design, needs to use ingenuity and exquisite craftsmanship to achieve a superior work.

This product has many hidden application fields, which are reflected in the military and people's livelihood domains.
In the military domain, it can be used for armaments manufacturing. For example, the ancient bow and crossbow mechanism was hidden in the equipment with exquisite structure, and it suddenly exerted power during wartime, making the enemy difficult to prevent. Today's military technology also has many exquisite designs hidden in equipment parts, which quietly play an effect in reconnaissance, combat and other links, or hide the body to avoid enemy detection, or secretly use force to enhance the performance of weapons.
In the field of people's livelihood, in the construction of buildings, some exquisite components are hidden between the beams and columns of houses. For example, the traditional tenon and mortise structure, although hidden inside the building, firmly supports the building and does not fall through wind and rain. And now many smart home devices, some components are also installed secretly, such as wiring devices in the wall, hidden sensors, etc., which do not disturb the beauty of the space, but can realize intelligent control and provide convenience for life.
Furthermore, in the pharmaceutical industry, drug carrier technology may have hidden applications. Some drug ingredients are wrapped in special carriers, which quietly release medicinal power in the body to avoid premature failure or adverse reactions, and accurately act on the lesion site. This is also a hidden application.
In the commercial field, in product anti-counterfeiting technology, some anti-counterfeiting labels are hidden in specific positions of product packaging, which can only be displayed with the help of specific tools or methods, which does not affect the appearance of the product, but can effectively prevent counterfeiting and maintain market order.
In terms of traffic, some safety aids of vehicles, such as hidden anti-collision steel beams, built-in sensors, etc., are hidden inside the vehicle body structure and play a role in critical moments to ensure driving safety.
Therefore, this product is used in many fields, which is of great significance to the development of society and people's lives.
