The main use of this product should be in many aspects. As recorded in "Tiangong Kaiwu", all kinds of creations in the world have their own uses, and they are all related to people's livelihood and national plans.
In the field of agricultural mulberry, many products are needed for farming. For example, the cloth produced by the loom can be used as clothing for the people to cover their bodies. Farmers use cloth to protect against cold winters and heat, to keep their bodies warm and cool, which is the basic need of people's livelihood. And cloth is also a trade of goods, circulating in the city, promoting commercial exchanges in the four directions, so that the people can communicate with each other and prosper the economy.
In metallurgical casting, the iron tools made are widely used. Such as agricultural tools, the iron plough breaks through the soil to cultivate the land and sow crops. The iron hoe weeds and protects the seedlings, which helps the smooth operation of agriculture. These iron tools greatly improve the efficiency of farming, increase the income of the fields and ensure the food of the people. And the casting of weapons is essential for national defense and armaments. Sabers, guns, swords and halberds are sharp weapons for soldiers to defend the enemy, protect the home and the country, and protect the peace of one side.
Ceramic products are also common in life. The dishes and cups used in daily diet are warm in texture and practical in storage. They are not only practical, but also exquisite in craftsmanship. They are also art treasures. They can be used as furnishings for people to enjoy and increase the elegance of life.
Furthermore, paper making and printing. Paper is the carrier of writing records. Literati and ink writers use paper to remember the beauty of mountains and rivers, the warmth and warmth of human feelings, and the depth of thought. With the success of printing, knowledge can be widely disseminated, students can read 10,000 volumes of books, and culture can be passed on and carried forward. It has made great contributions to educating the people and improving the world style.
All of these, the use of this product, whether it is related to daily use, production and trade, or national defense culture, is closely related to the livelihood of the people and the rise and fall of the country. It is indispensable.

The chemical properties of this product are various, so let's talk about them one by one. It is stable, and under normal circumstances, it is difficult to react violently with other things. Just like the old saying "stable as a rock", it can last for a long time without deterioration. This is one of its major characteristics.
Furthermore, it is soluble. In a specific solvent, it can gradually dissolve and disperse evenly, just like "ice and snow melt when they are warm", and it is integrated into the solvent to form a uniform system. However, its solubility is not universal, and it is only apparent in suitable solvents.
And it has reactivity. When encountering a specific reagent, it can initiate chemical reactions, or generate new substances, or change the state of chemical synthesis, just like "the wind and clouds change, and everything is renewed". The rate and degree of reaction often vary depending on the reaction conditions, such as the temperature, the pressure, and the presence or absence of catalysis.
Its acidity and alkalinity are also important chemical properties. Or acidic, which can be neutralized with bases, such as "yin and yang harmony", raw salt and water; or alkaline, which can interact with acids, and also obtain products of salt and water. The distinction between this acidity and alkalinity is related to the wide range of its uses.
Still has redox properties. In a suitable environment, it can be used as an oxidizing agent to take away electrons from other things and oxidize them; it can also be used as a reducing agent to supply electrons in the body, causing self-reduction, just like "giving and taking". This property is crucial in many chemical reactions.
In addition, its volatility cannot be ignored. At a certain temperature, it may be able to dissipate into gas, such as "light smoke drifting", which affects its preservation method and the environment of use.
This product is rich in chemical properties, and each property is related to each other. It has its own uses in different domains. Only when you understand the properties can you make good use of it and maximize its effectiveness.

The production process of this product is very delicate, and it is a collection of ingenuity and exquisite skills from past dynasties.
At the beginning, the selection of materials must be strict. The materials selected are all high-quality products, with solid texture and pure color. Just like the choice of jade, it must be flawless. Because of good materials, you can get good tools, which is the foundation of craftsmanship.
Then, in the stage of shaping, craftsmen use their minds and use their hands. Either carving or carving, or casting or calcining, according to the characteristics of the material and the charm of the object, so that it gradually takes shape. In the meantime, the depth of each knife and the weight of each hammer are all related to the final form. The heart of the craftsman is delicate and subtle, and strives to be unpleasant.
When the embryonic form first appeared, the decoration work followed one after another. Polished to make the surface as smooth as a mirror and feel warm to the touch; painted and inlaid to add gorgeous colors and brilliant colors. In this process, the collocation of colors and the layout of decorations follow the ancient methods, and they are integrated into the current aesthetic interest, which not only shows the ancient charm, but also has the style of the times.
And looking at the inheritance of this craftsmanship, the masters and apprentices teach each other, the oral teaching, and strictly abide by the essence of the technique, without the slightest deviation. In the meantime, craftsmen pour their efforts, treat each process with awe, and pursue the ultimate beauty with persistence. In this way, the unique style of the product is created, which makes it stand out among many products, exudes an enduring charm, and carries a profound cultural heritage and craftsmanship inheritance.

Today there is a product, I want to know how competitive it is in the market. In the state of the city, there are many competitors, and all kinds of products compete for beauty, each applying its own ability. If this product wants to stand out, it must have a unique quality.
Gu Yun: "If you want to be good at your work, you must first sharpen its tools." The quality of the product is like the dullness of the tool, which is crucial. It must be cast with fine materials and exquisite workmanship. If the material is poor and the craftsmanship is poor, it is like a boat of rotten wood, which is difficult to travel in the sea.
And the ability of the husband's product also needs to be needed in time. The needs of the city are changing rapidly, like an illusion of the wind and clouds. If a product can understand its changes, is timely and new, it can be in line with the public's will. In the past, there were things that did not change with the customs, stuck to their own feet, and were eventually abandoned by the city.
Furthermore, the reputation of the city is also heavy. In ancient times, there were merchants who built the world on faith. Their goods were beautiful and the price was real, and they did what they said. Therefore, customers all believed in them, and their business was prosperous. If the product is like this, it is based on integrity, genuine, and not deceived or deceived, then the customer will come from it, and the reputation will be self-fulfilling.
In addition, the art of propaganda should not be ignored. The fragrance of wine is also afraid of the deep alley. Those who are good at propaganda can make good things widely known. When you use ingenious methods to spread its advantages, attract the eyes of
The competition of the market is not the only one. All kinds of factors are intertwined with each other, like strands of silk, intertwined. To strengthen its competitiveness, it is necessary to carefully observe the city conditions, make good use of various policies, and persevere in order to win the favor of the city and win in the competition.

The storage conditions of this product are as follows: It should be placed in a cool and dry place, avoid direct sunlight, and keep away from fire and heat sources.
If you hide things, you should choose the place and place them where you are. This product is no exception. In a dark and dry place, you can avoid the invasion of moisture. Moisture, such as the gradual decay of the beetle, can damage the quality of the thing and damage its form and spirit. Direct sunlight, if the flame is forced, it may cause the product to change color and quality. For example, if Qiluo is exposed to the scorching sun, the color is easy to darken; the paste is exposed to the scorching sun, and the texture is easy to change.
As for fire and heat sources, both are serious troubles. Fire is like a beast, which can turn the product into ashes in an instant; fumigation by heat is also like a hidden worry, or causes the nature of things to change, and the effect dies out. Therefore, when storing this product, be careful and keep it away from fire and heat to keep it intact. In this way, the product can be stored for a long time without losing its use, so that it can be used when needed.
