thiophene, 2-bromo-5-phenyl-

Because I don't know the specific product referred to, the following is an example of "cinnabar", which is modeled on the classical style of "Tiangong Kaiwu".
Cinnabar, also known as Dan sand, is a common mineral. Its color is bright and red, and it has extraordinary characteristics.
The production of cinnabar is mostly found in mountain and river caves. Ancient mining people often ventured into caves to get this treasure. Its land is deep and dark, and it is very difficult to mine. The original cinnabar stones mined, large or small, are like strange stones, red in color and hard in quality.
The chemical properties of cinnabar are mercury sulfide (HgS). Its chemical composition is unique. For this mercury sulfide, mercury and sulfur combine in a specific ratio and structure. When heated cinnabar, mercury evaporates and separates easily, and sulfur changes accordingly. Cinnabar is relatively stable in the air, but when it encounters strong heat or specific chemical reagents, it changes immediately.
The use of cinnabar has a long history. In ancient times, the alchemists thought that alchemy was a wonderful product, hoping to obtain a medicine for longevity. In medicine, it has the effect of calming, calming the nerves, and detoxifying, and can treat palpitations and insomnia. And in the paint, its color does not fade for a long time, and it is often loved by painters, painting many handed down Danqing. As for the people, they also use cinnabar as a thing to ward off evil spirits, hanging in the room for peace.

The main uses of this product are diverse and exquisite. First, in war, it is often a weapon to defeat the enemy. As "Tiangong Kaiwu" says, the system of weapons is related to the rise and fall of a country. This product has been carefully forged by craftsmen, and it is extremely sharp. It can break the armor of the enemy. On the battlefield, it can enable soldiers to kill the enemy bravely, laying the foundation for the victory and defeat of the war.
Second, it is also a powerful assistant in daily labor. For example, when farming, it can help farmers to cultivate fields, make the land loose, facilitate sowing and irrigation, and then improve the efficiency of farming and protect the needs of people's livelihood. Craftsmen use it to process utensils, which can make objects more delicate and improve the level of craftsmanship.
Furthermore, in terms of decoration and display, it also has unique value. Because of its exquisite shape and exquisite craftsmanship, it is often placed in mansions and palaces to show the identity and taste of the owner. In the homes of dignitaries, such exquisite products are often adorned in the halls, creating a gorgeous and elegant atmosphere.
Or on the occasion of sacrificial celebrations, this product carries a solemn meaning. The ancients sacrificed it as a offering, worshiped the ancestors of the gods, expressed their devotion, prayed for well-being, and the prosperity of the family and the country. During the ceremony, it became an important medium to connect people and gods, adding to the solemnity and sanctity of sacrificial celebrations.
In short, this product plays an indispensable role in war, labor, decoration, sacrifice, and many other aspects. It is a treasure of both practical and cultural value.

The physical properties of this product are related to its texture, shape, color, weight and many other aspects. Looking at its texture, it is delicate and moist, such as the smoothness of suet, the warmth of tentacles, and the texture is high, as if it were made in heaven. Its shape is regular and square, with smooth and natural lines at the corners without the slightest hindrance; or it is flexible and changeable, like clouds and flowing water, showing ingenuity. The color is pure, without mottled colors, or shiny and white like jade, emitting a soft luster; or it is quaint and contains the charm of time.
When it comes to weight, it is moderately light and heavy. Holding it in the hand, there is neither too light and frivolous, nor too heavy and cumbersome. Between the pinch, the measure is just right. Its density is uniform, the structure is compact, and when it is knocked, the sound is crisp and pleasant, and the residual sound is curling, like the sound of gold and stone, which shows that its internal texture is solid and stable.
And its thermal conductivity is quite good, it is placed in a warm place, and the temperature rises quickly and evenly; if it is cold, it cools down slowly, and can maintain a relatively stable temperature. Its flexibility cannot be ignored. Although the texture is solid, it can be slightly bent without folding under moderate force, showing the characteristics of both rigidity and flexibility.
Such physical properties make this product both practical and ornamental. It is unique among many utensils, which is really a rare product.

Today there is a product, and there are many ways to combine it. In detail, one is the way to choose the best materials. The master of the material is the foundation of the product. If you want to make a good product, you must first choose the material carefully. As "Tiangong Kaiwu" says: "Anyone who makes a work must first acquire the material." When choosing a material, when examining its texture and performance, examining its source, seeking its purity, flawlessness, toughness and durability.
The second is the method of exquisite skill. Technique is like the ingenuity and skill of a craftsman when it comes to the product. Take the casting tool as an example, you need to be skilled in the control of the heat, knowing when the fire is fierce, it will melt, and when the fire is slow, it will condense. The book says: "When the heat is sufficient, the iron will melt." Managing the heat is not familiar with the heart, and it cannot be done after a long time of practice. And there is also a fixed method for forging and beating. The difference between weight and density is related to the quality of the product.
The third is the method of rigorous process. The formation of the product is not achieved overnight, and it must go through multiple processes. Each process is interlinked and cannot be slack in the slightest. For example, in the art of brocade, from silk reeling, dyeing, to upper machine weaving, each step needs to be done in sequence. If there is a slight mistake, the brocade will be disordered and all previous efforts will be wasted.
The fourth is the method of inspection and fine review. When the product is made, it must be inspected. Check its shape carefully for any defects; check its quality carefully for any defects. " "Tiangong Kaiwu" is also re-tested, thinking that only through this can qualified products be obtained. Or listen to the sound of knocking to distinguish between the virtual and the real; or test the performance to detect the good and the bad.
These numbers, material selection, skills, processes, and inspection, are all important methods for product synthesis. They complement each other and are indispensable. Only in this way can we create good products.

Looking at today's city, all kinds of products compete in it, and the competitiveness of this product is related to the rise and fall of survival. If you say it in ancient Chinese, the reason is also clear.
If you want to be competitive, the first thing is quality. Gu Yun: "If you want to be good at something, you must first sharpen your tools." As far as products are concerned, excellent quality is the foundation of a foothold. If you are a good workman forging a sword, you must choose fine materials, you must be diligent in forging, and you must be good at the heat, so that you can become a sharp blade that cuts iron like mud. The same is true for products, with good materials and exquisite craftsmanship, they can be favored by everyone. If you cut corners and make shoddy products, like a boat of rotten wood, it will not stand the wind and waves, and it will be abandoned by the market.
Second, the function will Products need to respond to people's needs and solve people's difficulties. In the past, Luban made saws. Because he saw that the serrated teeth of grass and leaves could break the skin, he thought of creating things to facilitate logging. This is an example of understanding needs and good function. Today's products, if they can detect people's hidden needs, introduce new ones, and add practical functions with ingenuity and ingenuity, will surely stand out. Such as the change of mobile phones, from the simplicity of calls to the completeness of intelligence, the functions are increasing day by day, so as to adapt to the changes of the world, it has become an indispensable thing.
Furthermore, the reputation of Yilong. "If people have no trust, they will not stand, and if the industry has no trust, they will not prosper." The reputation of the product is accumulated in integrity. When you wait for customers to be sincere, you will practice what you say, and after-sales is thorough, just like Meng Taste's treatment of people, you will love each other, and there will be no deception. Word-of-mouth is spread, fame is spread far and wide, and everyone admires its faith and strives to buy its products, and competitiveness will rise. On the contrary, if you deceive customers, you will be shoddy, and once something happens, it will be like a building falling, your reputation will be destroyed, and your competitiveness will also be lost.
And the price needs to be appropriate. "If you are expensive at the top, you will be cheap, and if you are cheap at the bottom, you will be expensive." The price is too high, such as hanging a bead in the sky, although it is beautiful, few people will care about it; if the price is too low, if the rubble is in the way, people will doubt its quality. When judging the situation, balancing costs, measuring supply and demand, taking the price of the mean, and making value for money, everyone is Tesco, which is the long-term way.
In summary, the products are in the market, of high quality, good work, reputation and price, such as the four wheels of a car, the wings of a bird, it is difficult to fly without one, so that they can have strong competitiveness, ride the wind and waves in the city, and sail away.
