Looking at its physical properties, it has everything. It is a rare product in the world. It is both practical and ornamental. No wonder it is cherished by everyone.

Looking at this product today, the simplicity of its craftsmanship needs to be carefully observed. "Tiangong Kaiwu" has a saying: "The craftsmanship in the world is made by the heart, the complexity of craftsmanship leads to the refinement of craftsmanship, and the simplicity of craftsmanship leads to sparse craftsmanship." Therefore, in order to know the complexity and simplicity of craftsmanship of this product, it is necessary to study the various links of its production.
If the raw materials of this product are collected, they need to involve mountains and rivers and foreign lands, and they need to be carefully selected, and the quality will be affected if there is a slight difference. This raw material is complicated. Like ancient good materials, they are often hidden in deep mountains and old forests, and it is not easy to harvest and transport them.
Furthermore, in the production process, if there are many processes, interlocking, and each process requires exquisite skills, there is no room for the slightest mistake, this process must be complicated. Such as porcelain firing, from billet making, trimming, painting, glazing, to kiln firing, every link is about success or failure. If the temperature control is slightly improper, all previous efforts will be lost.
Or the decoration and carving of the product, if it is meticulously crafted, it will be endowed with unique charm with ingenious skills, and the craftsmanship is also complicated. Ancient jade, craftsmen use delicate techniques to carve jade into exquisite utensils, which cost countless efforts.
However, if the raw materials are easy to obtain, the production process is few, and there is no need for superb skills, a little operation can be done, and this process is simple.
Therefore, the process of this product is complicated and simple, and it is necessary to comprehensively consider its raw material collection, production process, decoration and carving. You can't just look at its surface, you need to explore it in depth to know the truth of its process.

"Tiangong Kaiwu" is a scientific and technological masterpiece written by Song Yingxing in the Ming Dynasty, in which the use of many things is discussed in detail. Today, if you use its classical Chinese style to respond to the question of what should be paid attention to when using this product, it is roughly as follows:
Anyone who uses this product should first clarify its properties. Each cover has its own characteristics, such as gold is firm and stone is brittle, and water is soft and fiery. This product must also have its own unique properties, or be temperature-resistant, or tide-resistant, or be quiet and avoid moving. Be sure to study it first before you can use it well.
