As a common art, technology has its own special rules of beauty. Technology usually does not simulate or reproduce the objective target. Even if some technical products adopt actual genres, such as flowers and grass, birds and beasts, fish and insects, what it seeks is not the precise appearance of the target. It usually exaggerates and deforms the artistic techniques to make the target pictorial and decorated, so as to create something symbolic, or to reflect some abstract, loose and fuzzy feeling The art of feeling atmosphere. This shows that technology is a universal embodiment of art. In addition to being useful, they are mainly used to beautify the environment, enrich energy and cultivate sentiment. It's a rule of extraordinary beauty in technology.

Technology, calligraphy and construction all belong to the useful art, their useful value and aesthetic value are unified together, they all lay particular stress on reflecting one-sided emotion and one-sided world, reflecting people's quality, energy and emotion, etc. in form, they all occupy certain space, so they are classified as embodiment space art. Technical products have both useful value and aesthetic value, which refers to the daily necessities with aesthetic characteristics in appearance and color. Including household utensils, furniture, clothing, environmental layout, etc., which are attributed to useful technology.

Because the production capacity, accuracy and proficiency of workers of different factories are quite different, the technology proposed by different factories may be different for the same commodity; even the technology of the same factory during different periods may be different. It can be seen that technology is not the only product, and there is no difference between good and bad.

Variety of technical products:

1、 Basic technology:

Main function of forming commodity: casting or casting, assembling

2、 Modification technology:

1. Change data function: cold treatment, such as electroplating, etc

2. Modification of data structure: heat treatment

Technology is the method and process that workers use production tools to process or process various raw materials and semi-finished products, and finally turn them into finished products. The principles of the proposed technology are: leading in technology and reasonable in economy. This kind of uncertainty is not only different from sex, but also similar to art. Some people interpret technology as "the art of workmanship".
