The principle of all things has its own characteristics, and the quality of utensils is related to the use. The physical properties of the husband's products are mostly soft, brittle, light and heavy, hot and cold, and dry and wet. The strong ones have strong qualities and can withstand external forces and are not easy to fold. If it is a genus of gold and stone, it can be used as pillars and sharp tools to bear loads and break solid objects. Soft ones are flexible in nature, flexible and stretchable, such as silk and linen materials, which can be made into clothes for suitable use. When they are strong, they will follow suit and not compete with force. Strong ones have dense textures and are durable. If porcelain and iron can pass through the years without breaking, they can be handed down as tools. Light, easy to carry and carry, conducive to circulation, such as bamboo and wood, walking around without getting tired. Heavy, calm and heavy, with the effect of stabilizing, such as copper tripods and boulders, which can be placed in the courtroom, can show solemnity. Cold, it feels cold, its quality is cool, such as jade and metal, and it is cool when touched in summer. Hot, it contains warm and thick gas, if it is wood, it can be taken for warmth in winter. Dry, dry but less moisture, not perishable, such as dried vegetables and dried fruits, can be stored for a long time. Wet, containing moisturizing properties, such as fresh vegetables and fresh fruits, full of vitality, but easy to deteriorate, must be used quickly. Look at the physical properties of the product, when it is clear its strengths, avoid its shortcomings. Those who use rigidity should not make it too rigid and fold; those who use softness should not make it weak and useless. Those who are strong are good to protect, and can be passed on to future generations; those who are brittle are careful to protect, so as not to be destroyed in one fell swoop. Those who are light are suitable, and those who are heavy should be guarded. Temperature and cold, dry and wet properly, then the use of utensils, can do its best, no discarded material, no waste of human power, this creation is wonderful.

When something is produced during storage and transportation, all matters must be paid attention to. When storing, the first priority is the suitability of the environment. It should be dry. If it is too wet, the product will be perishable. If the wood is damp and moldy, and the grain is wet and moldy and worms. And the temperature should also be controlled. Extreme heat and cold can damage the product. If it is chilled, it must be stored at low temperature, otherwise it will rot quickly; while some flammable products may cause disasters under high temperature. In addition, the storage place should be well ventilated, and the turbid air will not dissipate, which can also cause deterioration. Secondly, it is essential to have an orderly stacking. Do not pile up in a messy manner, and place it according to the size, weight and category of the product. Heavy objects are below and light objects are above to prevent crushing; the same kind gathers together to make it easy to find and use. And the stacking should not be too dense, and passages must be left for handling and inspection. As for transportation, the choice of vehicles is very critical. According to the nature of the product, choose the one that suits it. If it is fragile, when transported with a buffer device, such as porcelain, it must be padded with soft objects to prevent it from being damaged by bumps. For liquid objects, the carrier must be tightly sealed to prevent it from leaking. The stability on the way should not be ignored. The driving should be stable to avoid the sudden turning of the brake, and the ship should be protected from the wind and waves. The escort must also be conscientious, always check the condition of the property, and deal with it as soon as possible if there is any abnormality. When loading and unloading, you must be especially cautious. Handle with care and do not treat rudely. Large and heavy objects should be assisted by equipment and operated in accordance with regulations to ensure the safety of the property and the safety of people. In this way, the property can be kept intact during the storage and transportation process.

"Tiangong Kaiwu" is a scientific and technological masterpiece written by Song Yingxing in the Ming Dynasty. Although it does not mention specific modern products, according to its rigorous attitude towards craftsmanship and emphasis on safety, it can be deduced that when using a certain product, the following safety operating procedures should be avoided. Where using equipment, you must first check its condition. For example, "Tiangong Kaiwu" is made with equipment, and it should be reviewed initially. When using the product, you must not act rashly, and act without checking its damage or whether the parts are firm. For example, the molds must be carefully checked before casting in the book. The same is true for our products, otherwise the parts will loosen and there will be risks. When operating, strictly follow the order. " The various processes in "Tiangong Kaiwu" are all sequenced, such as papermaking, pounding, papermaking, etc. If the order is messy, it will not be possible and it is easy to cause risks. When using the product, do not change the order at will. If the operation guide clearly states that a switch is turned on first and a parameter is adjusted later, but it is reversed, or the circuit may be overloaded, mechanical failure, etc. Furthermore, environmental adaptation is crucial. "Tiangong Kaiwu" records that the processes are adapted to local conditions according to time, such as salt production needs to be checked for the weather and utilization. When using the product, the environment is improper and there are hidden dangers. If the electronic product is placed in a humid place, it is easy to short circuit; if the mechanical product is placed in a dusty place, it may cause wear and tear to intensify. It is also important to use the finished storage. The tools contained in "Tiangong Kaiwu" are well hidden to facilitate reuse. After the product is used, it can be discarded at will, or the parts may be damaged or lost, which will be inconvenient and dangerous to use next time. If sharp tools are thrown at will, it is easy to hurt people. During operation, protection is also indispensable. Although the protective equipment of today is not detailed in "Tiangong Kaiwu", people also have simple protection during casting. When using the product, if you operate dangerous machinery, do not wear goggles, gloves, etc. Once something splashes or gets involved, you will be injured.

All the skills of creation are related to the finesse and subtlety of craftsmanship, and cannot be ignored. In the past, "Tiangong Kaiwu" had clouds. Those who are good at craftsmanship must use their tools, pay attention to their methods, and concentrate on them before they can become exquisite products. The production process of a man's goods depends first on the selection of materials. The good and bad materials are related to the quality of the goods. If you make wood tools, you must choose those with solid texture and beauty; if you are metallurgical silver, you should seek pure quality and no miscellaneous ones. If you choose the right materials, you will have half the effort. The second is the method of craftsmanship. All craftsmanship has its own rules. Take the casting tool as an example, you must first make the mold, the precision and coarseness of the mold, and the shape and spirit of the fixed tool. After melting and casting, it is very important to grasp the heat. If the fire is fierce, the object will be destroyed, and if the fire is weak, the quality will be sparse. And after casting, there is also the work of polishing and modifying, so that the utensils are smooth and delicate, showing exquisite. Furthermore, the craftsman's intention. Concentration, without distractions, is the foundation of creation. When the craftsman is working, he observes the slightest detail and strives for perfection. Every knife engraving, every painting, is devoted to hard work. Such as the work of embroidery, between the flying needles and the thread, full attention can be embroidered to produce a lifelike pattern. And the production process is not static, when it is time to adapt to local conditions. The world changes, the demand also changes, and the process must also be easier. The ancient craftsmanship may have those that can be passed down, but it also needs to be improved in combination with the convenience of the present before it can be used in the world. Therefore, the production process of the product is based on the selection of materials, the process is the method, the craftsman is the foundation, and the change is based on time. In this way, only then can we produce excellent things, which are beneficial to the world and will leave a name in history.
