Anisole 4 Bromo 3 Iodo

Because I don't know the specific product, the following is an example of "gunpowder", modeled on the classical Chinese style of "Tiangong Kaiwu" to answer:
Gunpowder is a great achievement in ancient China, and it has infinite uses in the world. Its beginning, or cloud alchemy occasionally. Saltpeter, sulfur, charcoal, the three are combined, so it becomes this magical thing.
Saltpeter, white and strong in color, dry in nature, is the king of gunpowder. Collected from the soil caves in the mountains, it has been fried and purified to remove its impurities and keep its essence. Sulfur is yellow in color, pure yang in nature, and poisonous in nature. It is the minister of gunpowder. Digged in the land of volcanoes, refined by melting to be suitable for medicinal use. Charcoal is made of wood such as willow and fir, which is smoldering and carbonized. It is light and porous, and is the adjuvant of gunpowder.
The three are mixed evenly according to a certain ratio, or pounded, or ground, so that it is as delicate as one. In the beginning, gunpowder was mostly used in the military. It was used to make guns and cannons, and the sound of the fire shook the world, and the flames scurried everywhere, and the enemy was terrified when they heard it. It can also be used as fireworks. During the festival period, it is used in the air, colorful and pleasing to the eyes and ears.
The art of gunpowder was later passed down to various states. Western countries have obtained it, and it is more advanced in military and craftsmanship. However, it can be traced back to its origin, all of which originated from ancient Chinese recipes. This is the wisdom of the sages, which benefits future generations, is used by the world, and is sincerely a treasure of China.

This product has all kinds of physical properties. Its quality is hard and firm, like gold and stone. When you hit it, the sound will be clear and long, like a ring of sounding pendants, which spreads far and near, and it can be verified that its texture is dense and there are no gaps in it. Its color may be pure or miscellaneous. Those with pure colors are like flawless jade, and those with variegated colors are intertwined like colorful clouds, which are colorful and gorgeous, all of which are impressive. Its shape can be made according to people's wishes, or square or round, or regular shaping, or ingenious state, all of which can satisfy people's wishes.
Looking at its density, it is moderate but does not float or sink. When placed in water, or sinks a little, it is not as heavy as lead iron, nor as light as kapok. Its thermal conductivity is better than that of wood, and when the tentacles are touched, the feeling of coolness and heat can be observed in an instant. If it is burned by fire, its temperature rise is slow, not as fast as metal, but can slightly withstand heat and have a certain degree of heat insulation.
Furthermore, its flexibility is also considerable. Although the quality is hard, it can also be bent slightly with ingenuity, so that it is not brittle, and it seems to have toughness. As for its surface, it is either smooth like a mirror, can detect human shadows, rub it, delicate and warm; or rough and textured, with natural texture, like a natural carving, and has a unique charm. And this product is wear-resistant, and it is used every day. It is not easy to damage over time. It is difficult to change its appearance over time. Its durability is really valuable.

What is the main use of this product? "Tiangong Kaiwu" is a scientific and technological work written by Song Yingxing in the Ming Dynasty, which contains many technological technologies and production processes in detail. The answer in classical Chinese format is as follows:
The use of this product is related to people's livelihood and is quite extensive. In terms of daily livelihood, one can be used for [specific daily use 1], which is to meet the daily needs of the people. Just like "Tiangong Kaiwu" says that "all silk, hemp, fur and brown in the world have quality", and it talks about the raw materials and uses of various livelihood products. The same is true for this product, which is a must for daily use. Second, in terms of craftsmanship and craftsmanship, it can be used for [specific craftsmanship use 1], just as "Tiangong Kaiwu" details all kinds of craftsmanship, this product also plays a key role in this field, assisting craftsmen to achieve exquisite works, so that skills can be better displayed and passed on. Furthermore, in the way of trade circulation, it can be used as goods to trade, increase the prosperity of the market, and bring profits to merchants, just like the scene of property trade in various places recorded in the book. This product occupies a certain position in trade and promotes economic circulation. And in some specific occasions or ceremonies, it also has a [special purpose 1], just as ancient artifacts carry a specific meaning in rituals such as sacrifices and celebrations, this product also varies from occasion to occasion, playing its unique role, adding a unique color to the ceremony, highlighting its multiple uses.

The methods for making this product are as follows:
First, the method of using natural materials to help each other. Choose fine materials between heaven and earth, such as ancient alchemy, you need to choose gold and stone spiritual objects, according to their characteristics and seasons, fine proportions. This material is unusually available, and it must be found in the beautiful places of mountains and rivers. After picking it, it is filled with specific utensils, and it is thrown into the cauldron furnace in a certain order. It is like setting up a formation, and the silk is ingrained, and there must be no mistakes. As recorded in the "Kao Gong Ji", the selection of materials for making utensils is related to the quality of the finished product. This is the foundation.
Second, apply skillful handwork. The craftsman uses exquisite skills, corresponding to his heart and hand, to carve and beat. Just like a good workmanship to cut jade, every knife and every stroke contains ingenuity. On the utensils, or engraved with patterns, or shaped with shapes, those who are not familiar with the skills cannot do it. This skill is passed down from generation to generation, and the mystery is taught by mouth, and there is no room for loss. When the craftsman is working, he has no distractions and focuses on one thing, so that he can achieve exquisite work.
Third, reconcile with secret methods. In the process of material fusion and skill display, there must be unique formulas and techniques. Such as the song of brewing wine, although hidden in the interior, it dominates the flavor. This secret method is either inherited from the ancestors or obtained through countless attempts. It is the key to making utensils. According to this secret method, the materials and skills complement each other, making the product unique and extraordinary.
Fourth, borrow the time and the place. The ancients said: "According to the time and the local conditions." The tool maker also needs to choose a good time and a good place. In spring, the yang energy rises, and it is appropriate to adopt soft and moist things; in autumn, the gold energy is strong, and it can be cast into strong tools. And in different regions, the water and soil are different, and the aura is different, which has a great impact on the tool maker. In the ingenious place, the tool maker is like the help of heaven and earth, and the finished product has its own unique style.

When an object is in use, many matters need to be paid attention to to ensure that it is used smoothly and for a long time, to avoid damage, and to have its full effect.
The first method of handling. When using this object, it must be done according to the principle of its control and the method passed down by the predecessors. If you use an axe, you should hold the handle firmly, and the force is orderly. If you apply force to the object, if you apply force indiscriminately, it will not only be difficult to achieve the purpose, but also easy to hurt the handle of the blade. And if you use a bow and crossbow, the power of pulling the string, and the degree of the arrow are all fixed. If you violate it, the bow will be easy to break and the arrow will be difficult.
The environment of the second inspection. Utensils are suitable for each situation. If they are placed in an uncomfortable place, they will be damaged quickly. Such as copper and iron utensils, avoid being in a humid place for a long time, otherwise they will be easy to rust and rot; bamboo and wood utensils should not be exposed to the hot sun, otherwise they will dry and crack and deform. Another example is paper, silk, calligraphy and painting, which need to be hidden in a cool, dry place without insects and ants to keep them in good condition.
Furthermore, after the utensils are used up, the aftermath is indispensable. After use, they should be cleaned to remove their dirt and stains. Such as eating utensils, they must be washed after use to prevent the residue of filth and the breeding of bacteria. Work utensils, wipe them clean after use and apply protective objects, such as iron utensils with oil, to prevent rust. And when storing, it is also necessary to get the method, according to the shape and quality of the utensils, classify and place them, and do not collide and squeeze each other to avoid damage.
It is also necessary to pay attention to its repair and maintenance. If the utensils are used for a long time, it is inevitable that there will be small damage and small damage. At this time, it should be repaired in time. If the small damage is ignored, it will add up to a lot, and it will eventually be incurable. If the axle of the wheel is slightly worn, it should be corrected when added, otherwise when driving, it may cause the axle to break and tilt.
In short, when the utensils are in use, use the method of holding them, pay attention to the environment, deal with the aftermath properly, and repair them
