The method of making a product is quite critical, and it is related to the quality and effectiveness of the product. The following is a detailed description of the ancient Chinese saying.
If a husband wants to make this product, the first thing is to choose materials. The material must be excellent and flawless. As "Tiangong Kaiwu" said: "It is difficult for a woman to cook without rice." If the material is not good, everything will be fine. It is necessary to carefully examine the nature of the material, which is brittle, moist, and thick. Choose the right material to be the foundation of the synthesis.
Secondly, in the process steps. When it is done in sequence, it is orderly. Between the steps, it is interlocking and cannot be wrong. Every step requires precise operation. Or melting, or carving, or splicing, all have their own methods. When melting and casting, it is crucial to control the heat. "If the fire is too much, the material will be destroyed, and if the fire is not enough, the quality will not be up to", and the heat must be moderate, in order to obtain high-quality materials. When carving, the knife technique also needs to be exquisite, according to the shape of the material, follow the trend, and carve the desired shape. When splicing, make sure to fit tightly and integrate.
Furthermore, it is related to the craftsman's skills and intentions. The craftsman should have exquisite skills, and his heart should not be distracted, focusing on the joint work. The essence of skills comes from long-term practice. " Exercise a thousand songs and then know the voice, watch a thousand swords and then recognize the artifact ". Craftsmen can only be familiar with the method of combining after years of practice. The heart lies in the reverence for the product, not cutting corners, not perfunctory. Every detail is devoted to the effort, so that it can become a good product.
Combined products, the selection of materials is the foundation, the craftsmanship is the path, and the heart of the craftsman is the soul. All three are combined, so that you can get the best products, which can be used in the world.

The stability of this product is related to many factors. "Tiangong Kaiwu" says: "All craftsmanship must first discuss the material, the quality of the material, and the foundation of the utensil." The stability of this product depends first and foremost on the quality of the material. If the material is high-quality, the texture is tough and uniform, and it is less affected by the outside world, and the stability can be guaranteed.
The material is clear, and the method of making it is also the key. "Tiangong Kaiwu" also says: "If you want to do something well, you must first sharpen your tools and make good use of your methods." If the production process is exquisite, the links are closely connected, and the process is standardized, the product structure can be stable. For example, the method of mortise and tenon, which fits tightly, does not need to be riveted, but can make the utensil firm
Furthermore, use and maintenance also affect stability. "Tiangong Kaiwu" has a saying: "When utensils are used, they can be protected for a long time." If the product is used properly, it does not exceed its bearing range, and regular maintenance can prolong its life and maintain stability. On the contrary, abuse of false protection can easily damage its structure and reduce its stability.
Environmental factors cannot be ignored. "Tiangong Kaiwu" mentions: "Everything is subject to the control of the environment." Environmental conditions such as temperature and humidity, pH, etc., have a great impact on product stability. High temperature and humidity can easily deform and corrode the material; acid and alkali imbalance can also damage its structure. Therefore, it is suitable for the environment and guarantees the stability of the product.
To sum up, the stability of this product requires the coordination of material, production, use and maintenance, and environmental factors to achieve a good state and durability.
