The chemical structure of this product is particularly delicate, just like the ingenuity of heaven. It is delicately linked by many particles into an orderly system, just like the ancient gods and craftsmen made by ingenious techniques.
Between the molecular structures, the atoms are interconnected and maintained by chemical bonds, like a tightly interlocked chain, which is very stable. The atoms are arranged in their own positions according to specific laws, in an orderly manner, like stars listed in the sky, unruly. The symmetry and harmony of its structure are like the decoration of a bell and a tripod, showing the beauty of simplicity and rhythm.
And looking at its functional groups, they are properly distributed and have their own abilities, like soldiers in an array, performing their duties. They interact with each other, or cooperate or check and balance, to maintain the characteristics of the whole in subtle ways. This structure gives the product unique physical and chemical properties, so that it can exhibit extraordinary performance in a specific environment.
And its spatial configuration is not a simple list of planes, but a three-dimensional level. Atoms stretch out in three-dimensional space to form a scattered structure, such as the stacking of pavilions and pavilions, with distinct layers. This three-dimensional structure not only increases its stability, but also expands the way it interacts with the outside world, making it more functional.
Such a chemical structure is truly a masterpiece of nature and science. It is similar to the heavenly book left by the ancient wise men. Every detail contains endless mysteries, which will be carefully explored by future generations to appreciate the wonders of heavenly creations.

In short, this product plays a key role in many aspects such as daily labor, construction projects, geography, and military operations. It is relied on by all walks of life. It is actually a widely used and important thing.

The physical properties of this product are related to its quality, shape and properties. The quality is its material composition. Or it is gold, strong and tough, wear-resistant and corrosion-resistant, like an ancient weapon blade, mostly made of fine iron, which has survived through the years and is sharp; or it is wood, with natural texture, warm and simple, like the wood of Zinan, which can be used for beautiful utensils and exudes a quiet wood fragrance. Those who are like, say its shape and state. Or it is square, well-behaved, stable and dignified, like city bricks, built walls to defend against foreign enemies; or it is round, flowing naturally, smooth and rimless, like pearls, radiant, and good for decoration. Those who are sexual refer to its characteristics and performance. Heat resistance, or good heat conductivity, rapid heat transfer, such as copper ware, when cooking, can make food quickly cooked; or excellent heat insulation, can keep warm and cold, such as pottery pot, holding hot soup without burning hands. Electricity, or good conductivity, can pass current, into the power of the circuit, such as silver wire, in all kinds of equipment to transmit electricity smoothly; or good insulation, can resist current, protect people safety, such as bakelite, often electrical shell. Chemical properties, or corrosion resistance, long-standing outside, not with foreign objects should be damaged, such as porcelain bottles, weathered the wind and rain and the color of the glaze remains the same; or easy to change, in contact with specific things that change its shape, such as alkali and acid, wonderful changes. This is the product of the material nature of the important person, in use, when careful observation and good use of it, in order to do its best, suitable for its needs.

The method of combining a certain product is quite important. Looking back at the past, each has its own method for the inheritance of skills.
First, the way of selecting materials. The ancient good work is extremely cautious in the selection of materials. It is necessary to seek things of fine quality, such as swords, choose iron when it is pure, and if there are few impurities, the blade will be sharp and tough. " According to Kaogong Ji: "There are six levels of gold, six points of gold and tin make up one, which is called the unity of the bell and tripod; five points of gold and tin make up one, which is called the unity of the axe and catty; four points of gold and tin make up one, which is called the unity of the halberd; three points of gold and tin make up one, which is called the unity of the big blade; five points of gold and tin make up two, which is called the unity of the killing arrow; and half of gold and tin, which is called the unity of the flint." This is to say that different utensils are used for different purposes, and the proportion of materials selected is different. The product is combined, the selection of materials is the foundation, and the good material is half the work and double the work.
Second, the order of production. Everything has an order, and it cannot be disordered. For example, to build a palace, first set the base site, second stand the wooden frame, and then cover the tiles to build the wall. "Building French Style" details the system of architecture, from the foundation to the roof, every step is standardized. What to do first, and then what to do, in order, you can be well. If the chaos is reversed, it will lead to twice the result with half the effort, or even fail.
Third, the essence of skill. Craftsmen need to be skilled and skilled. Embroiderers, with fine stitches and exquisite color schemes, can embroider vivid pictures. Porcelain makers, who are familiar with the heat, can burn porcelain with radiant texture and pleasing color. In the past, Jingdezhen porcelain workers, with their exquisite skills, made porcelain famous all over the world. This all depends on the craftsman's concentration on research and continuous sharpening of skills, in order to make the product exquisite.
Fourth, the method of blending. When a variety of materials or processes are matched, blending is crucial. Such as winemaking, the ratio of wine koji to grain, fermentation temperature and time, etc., all need to be accurately grasped. All elements are properly blended to produce a mellow wine. If the pigment is blended, the color ratio is slightly poor, and the original color is lost.
All these, the selection of materials, the order of production, skills, blending, etc., are all important methods for product blending. They complement each other and are indispensable. Only in this way can we produce excellent products.

Looking at today's city, all kinds of products are competing in it. If you want to know how competitive a product is, you need to look at all the ends.
The first to look at its quality. Quality is the foundation of a product. If it is fine gold and jade, flawless and strong, it will be favored by people. In the past, there were good workers who made swords, with excellent selection of materials and fine forging. Their swords were incomparably sharp and cut iron like mud. This sword is famous all over the world for its high quality. The same is true of the product. The texture is excellent, the use is durable, the performance is outstanding, and they can outperform others.
The second to look at its use. The user, the function of the product is also. It is necessary to meet the needs of people at the moment and facilitate life. Like the water wheel of ancient times, the water is diverted from the canal to irrigate the fields, and the farmers can get it conveniently, and the harvest is worry-free. Today's products, if they can meet people's urgent needs and solve people's difficulties, such as intelligent things, convenient communication, and efficient office work, these products are practical and self-strengthening.
Furthermore, it depends on the price. The price is moderate, and if it is worth the money, everyone wants to buy it. In the past, Jia people sold things at low prices and good quality, and everyone flocked to them, and their stores were very popular. On the contrary, the price is high and the quality is inferior, and few people care about it. It is the way of pricing, which is related to the rise and fall of the product.
And look at its reputation. Reputation, word-of-mouth is also. If everyone praises it, it will be famous far and wide. The old store in ancient times operates with integrity, and the children are not deceived. Over the years, it has accumulated a good reputation, and visitors from all over the world believe in it. The reputation of the product is like a boat sailing downwind, and the road to the market is smooth.
In addition, new is also important. Times change, and people's preferences change. If the product can be updated, like the craftsmen of ancient times, who constantly improve their skills and produce novel things, they can keep up with the trend and not fall behind.
To sum up, if the product is in the market, it is necessary to be competitive, of high quality, good use, suitable price, good reputation and innovation. Only by having all of them can we cross the market and compete with the strong.
