The main uses of this product can be roughly divided into various categories. The first is the convenience of life, such as at home, which can be used as an aid for daily use and make everything more smooth. The second is the help of labor, which can increase efficiency and reduce manpower in agriculture and handicraft. The third is in war, which can be used as a weapon or a defensive tool, which is related to the safety of victory and defeat.
As mentioned in "Tiangong Kaiwu", all things in the world have their own uses. Taking agricultural tools as an example, the genus Leiyu can break the soil and plow, which benefits the sowing of seeds and the planting of seedlings. It is the foundation of farming and is related to people's livelihood. And textile equipment can turn silk and linen into cloth, making clothes for people and covering their bodies, which is related to people's livelihood.
Furthermore, in architectural construction, axes and saws can cut wood for wood, and masonry tools can build walls and houses, making people have a place to live. And utensils can also be the carrier of cultural inheritance. Those with exquisite craftsmanship carry skills and aesthetics, and are passed down from generation to generation, passing on civilization endlessly.
In commercial trade, this product may be a traded product, which is exchanged with each other, promotes the circulation of four directions, and increases the accumulation and dispersion of wealth. Its use runs through various fields such as life, production, military, culture, and trade. It is of great significance and indispensable to all people in the country and the country.

When making this thing, you need to pay attention to many things. The first choice of materials, the quality of the material, is related to the quality of the thing. When choosing high-quality materials, those with tough texture and fine texture are better. If the material has flaws, even if the skills are exquisite, it is difficult to become a good product.
In the production process, it must be rigorous and orderly. At the beginning of the material, the size must be accurate, and the slightest difference may cause the overall inaccuracy. When cutting, the knife method should be stable and uniform, so that the incision is flat and smooth.
The subsequent carving is the key. It needs to be carefully carved according to the shape of the design. When transporting the knife, the priorities are all exquisite. If the force is too strong, it is easy to damage its shape; if the force is too light, it is difficult to show its charm. And the smoothness of the lines and the symmetry of the pattern need to be carefully considered.
Furthermore, the splicing combination should not be underestimated. The fit of each part must be tight, in order to be stable and durable. The mortise and tenon structure used in the middle should be exquisite and appropriate to increase its firmness and not to make it loose and disjointed.
In the firing or processing process, the control of temperature and heat is of paramount importance. If the temperature is too high, the object is easy to deform and crack; if the temperature is insufficient, it is difficult to achieve the ideal texture and color.
During the production process, the craftsman's heart also needs to be focused and peaceful. If you are impatient, it is difficult to notice the subtleties and easy to leave regrets. Only with awe and exquisite skills can we make good products.

It is generally difficult to determine the market price of this product among the people in the market. The change in the market price is like the impermanence of the situation, and it depends on many reasons.
If there is a state of supply and demand, it is one of the main reasons. If everyone wants this product, there are many people who need it, and there are few people who supply it, the price will increase; on the contrary, if there are many people who produce it, but there are few people who want it, the price will drop.
Furthermore, the quality of the material is also related to the price. Those who use high-quality materials and are meticulously crafted will have a high price; if they are second-rate, the price will be low.
And the difficulty of making it will also affect its price. If the production requires clever skills and time-consuming, the price will always be expensive; if the production is simple, the price will be average.
And the passage of time and the change of fashion also have an impact on the price. Whenever everyone still likes this thing, the price may rise; if the fashion changes, the price may fall.
As for the items involved in "Tiangong Kaiwu", although it is difficult to determine the specific price of this product, it is common sense. If it is an ordinary product, it is not difficult to make, the material is ordinary, and it is not something that people are seeking at the time, its price is medium or average, according to the current measurement, or it is worth a few dollars in silver; if it is an exquisite tool, with high-quality materials, complicated production, and in line with the meaning of the people at the time, the price should be doubled, or the value should be two or even tens of taels in silver. However, this is all speculation, and the market price is not constant. Only by carefully observing the market can we obtain its approximate value.

The storage conditions of this product are as follows: It should be placed in a cool and dry place, away from direct sunlight, to avoid the risk of moisture and mildew. If it is hot in the summer, you should pay special attention to the temperature and humidity of the environment. In the warehouse, the temperature should be controlled below 20 to 5 degrees Celsius, and the humidity should not exceed 60%.
And the storage place should be kept away from fire and heat sources to prevent quality variation due to high temperature. It should also not be stored with odorous things, so as not to smell together and damage its inherent flavor. In the storage place, it is necessary to keep air circulation, so that the breath is unobstructed, so as not to cause depression and rot.
If this product is fragile, it must be handled with care during storage and handling, so as not to cause collision and fall to prevent damage. In addition, the products should be arranged in an orderly manner according to their category and batch, which is easy to find and use, and can grasp their storage status in time. If there is any abnormality, they can be disposed of quickly. In this way, the product can be maintained in good quality during storage for timely use.
