The main uses of this product are as follows.
One can be used to help with labor. "Tiangong Kaiwu" has a saying: "The silk, hemp, fur and brown in the world are all of quality, so that the special face and color can be used. It is said that those who do not work hard in creating things, I do not believe it." When it comes to many utensils and materials, they can make everything more convenient and efficient when working. Take farming as an example, the genus of Leiyu can break the soil and plow it, help farmers cultivate the fields, improve the efficiency of crops, and enable the land to be cultivated intensively, so that it is expected to harvest a lot. Another example is the tools used by craftsmen, such as axes, sawing and chiseling, which can precisely process wood, build houses, and create utensils, so that the work of civil engineering and the work of hundreds of workers can be carried out in an orderly
The second can be used for decorative embellishment. "Pearl gold and silver, adorned on the hair and skin; splendid Luo Qi, on the body." Many products, such as beautiful silk fabrics, are woven with exquisite patterns and colorful, can be cut into ready-to-wear clothes, worn on the human body, showing a graceful and luxurious state, adding to the wearer's style; and all kinds of jewelry and jade, finely carved, or for accessories, or for ornaments, placed indoors or worn on the body, can create an elegant atmosphere and enhance the style of life.
The third can meet the daily needs of life. People take food as their heaven, and cookware, such as a cauldron, is used to cook food, turn ingredients into delicious dishes, and nourish the body. And tableware such as dishes, bowls, cups and other tableware are convenient for eating and drinking. Furthermore, the beds, tables and chairs required for living enable people to rest and sit, build a comfortable living space, and are indispensable in daily living.
The four can be used for trade and exchange. The products in the world are different, and they are special to one place or needed elsewhere. It is to transport local products to other places through trade and exchange them for what is needed. "Where the boat and car arrive, the manpower is connected, the sky is covered, the earth is carried, the sun and the moon are illuminated, and the frost and dew are on the team. Anyone who has blood and qi will respect his relatives. Therefore, it is called matching the sky." This trade between China and China allows products to circulate in all directions, enhancing exchanges between various places, and promoting economic prosperity and development.

The method of making this product follows the ancient method and integrates many exquisite techniques.
First take the high-quality material, this is the foundation. As "Tiangong Kaiwu" said: "Where the casting mirror is made, the mold is made of gray sand, and the copper is made of tin." The quality of the material is related to the quality of the product. Therefore, the material selection must be carefully selected to ensure that the texture is pure and free of impurities.
Then perform the melting technique. Put the selected material in the furnace and smelt it at a moderate temperature. "The fire is fierce, and copper is easy to melt. However, it needs to be controlled accurately. If it passes, it will damage the quality." It is necessary to be good at detecting changes in the heat and adjusting it in a timely manner to make the material fully fused and turned into a uniform melt. This process requires the smelter to have rich experience and exquisite skills in order to be just right.
When the melt is ready, the casting will be done. A special mold is prepared, with precise shape and fine texture. The melt is slowly injected into the mold, and the action should be steady and slow, so that the melt fills all parts of the mold evenly, without omissions or bubbles. After casting, wait for cooling to form.
After forming, repeat fine processing. Or polish its surface to make it smooth like a mirror, "polish it to make it light, radiant and radiant"; or carve its texture to make it exquisite. When processing, the craftsman needs no distractions, with high concentration and skills, to give the product a unique charm.
Through these various processes, interlocking and meticulous, this excellent product is obtained. Every step is in accordance with the ancient method, inheriting the essence of thousand-year-old craftsmanship, integrating traditional wisdom and craftsman ingenuity to achieve a unique combination method.

Looking at this product, its market price range is really difficult to determine, due to the influence of many factors. According to Guanfu's "Tiangong Kaiwu", the price of all kinds of products often varies with time, place and quality.
Now on this product, if the source of its raw materials is widely available and easy, the price may be slightly cheaper; if its source is rare and difficult to mine, the price will tend to be high. For example, mineral products, if the origin is rich, the price will be flat, and if the origin is remote and the reserves are small, the price will be high.
Furthermore, the production work also involves the price. If the process is simple, it costs less manpower and material resources, and the price is close to the people; if the process is complicated and meticulously crafted, such as ancient porcelain making, it has gone through many procedures, and requires good craftsmanship, the price is not expensive.
And the state of market supply and demand is also the key. There are many who need it, but there are few who supply it, such as rare treasures, the price will jump; if the supply exceeds the demand, such as in the year of normal fruit and vegetable harvest, the price will be low.
From this perspective, the price range of this product may be as low as the minimum to meet the needs of the public; or as high as the value of thousands of gold to show its rarity and excellence. However, if you want to know the details, you still need to deeply study the raw materials, processes, supply and demand, etc., in order to obtain its approximate price range.

When something is stored and transported, all the things to pay attention to must be detailed.
When storing, the first priority is the suitability of the environment. If it is placed in a wet place, it is prone to rot. Therefore, in the warehouse, it must be properly dry and damp, and well ventilated. And it is necessary to prevent the damage of rats and insects, which can damage the objects. In addition, the method of stacking is also important. When it is sorted in an orderly manner, it should not be disorderly, so as to facilitate the search and use, and to avoid the danger of extrusion damage.
As for transportation, stability is essential. The transportation equipment must first be checked in good condition, the axles are strong, and the ropes are stable before it can be set off. On the way, prevent bumps and collisions. If it is a fragile thing, you should especially take care of it and place it with a soft cushion. You must also pay attention to the weather, in case of wind, rain, frost and snow, when there is a protection policy, do not let the object be damaged by it. And the escort must be careful and attentive, not slack off negligence, and monitor the contents at any time to prevent unexpected changes.
The journey of transportation is different from near and far, and the schedule must also be planned accurately. If it is delayed for too long, it may cause the deterioration of the object, or miss the schedule of other things. Therefore, when on the way, it is appropriate to arrive quickly and orderly, and to arrive at the scheduled time.
In general, this item should not be ignored in the storage and transportation room, environment, protection, and planning. If you manage it carefully, you will be safe.
