The main user of this product, "Tiangong Kaiwu" has a taste of the cloud: "Silk, hemp, fur, and brown in the world all have qualities, which make it possible to have a unique color. I don't believe it if I say that the creation of things is not laborious." Looking at it, we know that dyed things have a wide range of uses.
First, along with clothing, it is very important. In ancient times, the people first used animal skins and leaves to cover their bodies. Later, the color of textiles and fabrics began to be plain. However, people's love for beauty has been there since ancient times, so they have sought various dyeing methods to make clothing colorful. If it is dyed in vermilion color, it is bright and dazzling, and on solemn occasions such as sacrifices and celebrations, it is worn in vermilion clothes to show respect; dyed in green and blue color, it is fresh and elegant, and it is worn every day to show the beauty of nature. Clothing has various styles due to dyeing, which can show identity and preferences, and become an important carrier of culture and aesthetics.
Second, it is also very useful for the decoration of utensils. In ancient times, ceramics and lacquer ware were often decorated with dyeing methods. On the ceramics, they were dyed with colored materials to paint landscapes, flowers and birds, and figures, which were lifelike and added artistic charm to the utensils; lacquer ware was decorated, and the dyed lacquer was smeared layer by layer, or black and red, or colorful, making the lacquer ware exquisite and luxurious, both practical and ornamental.
Third, in the ceremonial system, it is indispensable. Dynasty sacrifices, the color of the sacrifices and the color of the sacrificial clothes are customized. For example, the color of the sacrifice to the sky is blue, and the color of the sacrifice to the ground is yellow. This is based on the five elements and yin and yang. The dyed objects are in line with the ceremonial regulations, highlighting the order of human relations in heaven and earth, and maintaining social hierarchy and cultural inheritance.
All these, it can be seen that this product is mainly used to enhance the color of clothing, decoration of utensils and etiquette. It plays a key role in human life, culture and system. It carries history and civilization and extends endlessly.

Its quality is hard, like the strength of gold and stone, it is solid and calm to touch, and when it is knocked, the sound is crisp and pleasant, like a ring of ringing, it spreads in the four corners, and its sound is clear and continuous for a long time. The cover is caused by its dense and orderly internal structure and strong attractive force between molecules.
Look at its color, pure and warm, or white like suet, delicate and soft, light but not shining; or green like jade, fresh and full of vitality. This is due to the different types and proportions of elements contained, and the work of creation shows this beautiful state.
In addition, its chemical properties are quite stable. In the common acid and alkali environment, it is still calm and unmoved, just like a gentleman who keeps integrity and is not disturbed by foreign objects. However, when encountering a specific strong oxidant, it can also respond to it, just like the combination of rigidity and softness, although firm and soluble.
And its melting point is quite high, it needs to be calcined with fire, and it can only be melted after high temperature. This is like the exercise of a man of lofty ideals.

There are things today, and in the process of synthesis, those who should pay attention to all kinds of things must pay attention to them in detail.
The choice of the first heavy material. The material is the foundation of the thing, and its quality is good or bad, which is related to the quality of the finished product. It is necessary to choose excellent materials, which are firm in texture, stable in nature and not easy to change. If the material is flawed, or soft and brittle, even if you have ingenious skills, it is difficult to make a good tool. For example, when making a sword with good craftsmanship, you must seek fine iron, and the steel is pure and beautiful, so that you can cast a sharp blade and cut it like mud.
The second is the observance of the law. There are fixed rules for the method of synthesis, and there is no difference at all. From measurement to carving, from splicing to decoration, all follow the ancient methods, or follow the wonderful recipes of the predecessors. If you build a palace, the size of the beams and columns, and the fit of the mortise and tenon, all follow the rules, so that the house is stable and will not fall over the years.
Furthermore, the craftsman's skills should be fine. The skill of the craftsman is the sublimation of things. The heart is as meticulous as hair, and the hand is as skillful as a god, so that the ordinary can be turned into magic. The knife and hammer are carried with rhythm, and the carving and carving are exquisite. Those who are good at writing are wielding a few words, the pen is tactful, the ink rhyme is natural, and it is well-made.
Also need to pay attention to the suitability of the environment. Dry materials are easy to crack, and wet things are easy to rot. Where it is made, it should be If you are in a place of extreme cold and heat, the materials are vulnerable and the work is difficult to apply.
When it is combined, you should concentrate on it and get rid of distractions. If you are impatient, it is difficult to achieve perfection. You must concentrate on it and face it with awe, so that you can obtain the essence of the thing and become a handed down product.
To sum up all the above things, you should pay attention to the combination of this thing, and take into account all aspects, so that you can make a good product and live up to your efforts.
