Disodium (3Z)-5-Amino-6-[(E)-{4'-[(E)-(2,4-Diaminophenyl)Diazenyl]-3,3'-Dimethylbiphenyl-4-Yl}Diazenyl]-4-Oxo-3-(2-Phenylhydrazinylidene)-3,4-Dihydronaphthalene-2,7-Disulfonate

The chemical structure of this product is just like the wonderful structure of heaven, with a unique shape. Looking at it, it is like the delicate carving of nature, hidden in the universe.
Its core structure is cleverly connected with various elements, as if the stars are listed in the sky, in an orderly manner. The atoms are connected by chemical bonds, which are stable and not lost in agility, just like the ancient tenon and mortise structure, which fits infinitely. On the main chain, the side chains are derived, each having its own position and performing its own duties, like the veins of mountains and rivers, criss-crossing and clear.
The distribution of functional groups is also unique. At the key check point, it plays a unique role, or like the rooster of Sichen, which leads to the beginning of a chemical reaction; or like the needle of the sea, which stabilizes the properties of the system. These functional groups give the product special properties, or have hydrophilicity, which can blend with water, just like the joy of fish and water; or are hydrophobic, away from the infiltration of water, just like the lotus leaf repels water.
The spatial configuration of molecules is not a simple arrangement of planes, but a delicate three-dimensional construction. It may be like a winding spiral, containing endless mysteries; or a cage-like closure, hidden in it. This unique spatial structure not only affects the interaction between molecules, but also determines many macro-manifestations of the product.
Overall, the chemical structure of this product is a combination of refinement and complexity, just like something made in heaven, and it interprets unique wonders in the microscopic world, laying a solid foundation for its wonders in various fields.

The main purpose of a product is related to its function and value in the world. "Tiangong Kaiwu" talks about various products, each of which has its own unique use.
Taking Nongsang as an example, silk weaving products are mainly used in clothing making. Silk strands are fine and soft, woven clothes are warm in winter and cool in summer, comfortable to the touch, and colorful, which can cover the body and beautify the world. The ancients often wore silk-woven clothes on important festivals and ceremonial occasions to show their solemnity and identity. Furthermore, silk fabrics can also be used to make curtains, quilts, etc., to add elegance and warmth to the residence.
Ceramic products, one of which is used for eating utensils. Porcelain bowls and porcelain plates are clean and beautiful, and are not easy to corrode. They are durable and can be used for daily diet. Second, ceramics are used for decoration. Exquisite porcelain vases, porcelain carvings, or placed in halls, or aged in several cases, show elegance, can be used as treasures for interior decoration, and enhance the charm of the room.
Metal products, such as iron farming tools, are the key to farming. Ploughs, hoes and other utensils help farmers reclaim land, cultivate and harvest, greatly improve agricultural production efficiency, and are related to people's livelihood and clothing. Copper tripods, bells and other ritual utensils, on solemn occasions such as sacrifices and celebrations, have important symbolic significance, demonstrate status and power, and carry cultural traditions and spiritual connotations.
Paper is also widely used. The first is to write records. Since Cai Lun's improvement of papermaking, paper has gradually become a text carrier, enabling knowledge to be passed on, scholars to write books, and cultural classics to be passed down to future generations. Secondly, paper can be used for packaging, which is light and convenient, and can wrap all kinds of items. There are also entertainment items such as kites made of paper, which are used for entertainment and add fun to life.
All these products have various uses, and play an indispensable role in many aspects such as clothing, food, housing, transportation, cultural inheritance, and ceremonial celebrations. They promote the continuous development and progress of human society.

The ideal nature of the husband's product is multi-ended. The first is firmness and durability, which is the basic quality. In the past, the production of utensils, all sought to last for a long time without damage. Like the sword of ancient times, it has been honed over the years, and it is still sharp to learn from. This is the proof of firmness. If the product is not strong, it will be destroyed before it is used for a long time, and it is useless. It is also difficult to sell in the city.
Second, it is convenient and practical. Things are used by people, and they should be suitable for people's needs. Looking at the agricultural tools of ancient times, they are exquisitely designed, easy to farm, and can save manpower and increase efficiency. The same is true for today's products, such as the convenience of transportation by boat and cart, and the help of equipment for labor, all of which are practical. If you have a gorgeous watch without practical ability, it is not
Furthermore, beauty is also valued by the product. Beauty is not just about the gorgeous appearance, but also the meaning of harmony and elegance. Ancient porcelain, beautiful in shape, exquisite in decoration, pleasing to the eye and pleasant to use. The product is both beautiful and useful, and it is good.
And the product should be economical. It takes money and effort to make things. If the cost is too high, the price is high and it is difficult for people to buy, it will be unfavorable to circulation. Therefore, it is necessary to make excellent products at a reasonable cost, so that the price is worth the money and everyone can use it.
It is also safe and essential. Whether it is food or daily use, it must be harmless to people. The ancient winemaking techniques were strictly adhered to to to ensure that the wine was pure and non-toxic. Today's products should be the same, ensuring the safety of users is the right way.
All these, such as firmness, convenience, beauty, economy, safety, etc., are the ideal properties of the product. Those who make products should take into account all aspects in order to make good products and use them for the world.

When a certain utensil is in use, it is quite important to pay attention to all kinds of things, which are related to the convenience of the user and the longevity of the utensil. Let me tell you one by one.
The first thing to recognize is its nature. Each utensil is unique, or temperature-resistant, or corrosion-resistant, or brittle, or strong. For example, gold is soft and extensible, and if it is applied with force, it is easy to deform; while porcelain, although exquisite, is not resistant to heavy blows. A little carelessness will cause cracks. Therefore, know its nature before use, and act according to it, so that it can be used well.
The second is suitable for its use. Everything has its own use, and each is suitable for its own use. If a hoe is used to reclaim the field, it should not be used as a blade to cut objects; if a pen is used for writing, it should not be used as a hammer to hit nails. If you force an utensil to perform beyond its ability, it will not only be difficult to achieve, but also damage the utensil.
Furthermore, use it properly. Use the method properly, and get twice the result with half the effort, and the utensil can last for a long time. Like a sword, use a clean wipe and oil to prevent rust; wood, do not leave it in a damp place, so as not to cause rot. When using things, the method should also be appropriate, and you should not do it wantonly.
Fourth, maintenance is essential. After the utensil is used, it should be taken care of. Wipe it often to remove its dirt; repair it in a timely manner Such as the genus of a car and boat, regular maintenance can ensure smooth driving; clothing and other accessories, washed and dried according to law, can prolong their life.
It is also appropriate to store. When storing utensils, choose a suitable place. Flammable objects, keep away from fire sources; fragile utensils, keep them in a stable place. And different utensils, classified and stored to avoid confusion and collision, damage to their integrity.
In short, when utensils are in use, they should be sensible, applicable, obtained, nurtured, and well preserved. Only by paying attention to all kinds of things can they be used to their full potential, and they can accompany us for a long time and add color to all things in life.

In the ancient times, the ancestors took many natural things, such as wood, stone, bone, and pottery. Wooden, flexible and easy to carve, can be made into utensils, such as a spider, to help cultivation; stone, hard and wear-resistant, can be ground into sharp blades, used for fishing and hunting. Bone can be engraved, and pottery can hold things, all of which were commonly used at that time.
Next, the process needs to be clarified. The method of casting utensils, there is the art of fan casting. First make a mold with mud, engrave its patterns and shapes, and then wrap it in mud to make an outer model. When it dries, inject the copper liquid into it, cool it, and break the model. This technique requires precise control of the heat and the proportion of liquid copper in order to make a beautiful tool. There is also a method of forging, which is to hammer the metal to make it form. Repeated beating can increase the toughness and strength of the metal. For example, forging a sword requires thousands of refinements before it can be cut into iron like mud.
Furthermore, the craftsman's skills and experience are the key. The heart of a good craftsman is fine. It can observe the texture of the material, follow the trend, avoid its flaws, and develop its strengths. And it can be familiar with the steps of the craftsmanship, with no difference. From the design of the tool to its completion, it is carefully done. If you make jade, you need to follow the color, texture, and design of the jade, and carve it with a mound. Every knife contains ingenuity.
There is also the need for collaboration. The making of utensils cannot be done by one person, and everyone divides and collaborates, and each performs its own strengths. Material collectors, model makers, casters, forgers, etc., each perform their own duties, so that they can advance in an orderly manner. Everyone is single-minded, and together they are the foundation for the completion of utensils.
All these, the selection of materials, craftsmanship, craftsmanship, and collaboration, are all methods of utensils production, and none of them are indispensable. Only by using them together can we create excellent utensils to meet the needs of the world.
