Generally speaking, the table reduction method mostly uses concrete graphics.

Sporting goods, libraries and Lv Wen shops are all places with simple services. In logo design, choose your own representative visual graphics and express them directly with expressions, so that the meaning of the logo is clear and the content is clear at a glance.

Symbolism refers to the use of graphics (including concrete and abstract) to indirectly express things, or to express their quality and efficiency; Or express its meaning, concept, etc.

The symbolic technique of visual plastic arts is to express the essence or meaning of things through analogy or metaphor.

The method of knowing is suitable for expressing something that cannot be declared and has no exact symbolic image. The method of knowing is realized by entering association. The techniques used are also symbols and metaphors, but the difference is. The way to know is usually not to express it from the front, but to use some external images that seem irrelevant to convey the content, thus breaking some fixed routines and making the logo look novel, unique and extraordinary. The symbol of travel insurance company is an umbrella. It seems ordinary, but it has a lot of meaning. Umbrella can shelter people from the wind and rain, remind people of the reliability of insurance companies, and thus have a good impression on insurance companies; At the same time, the umbrella reveals the business nature of insurance companies.

In the traditional culture of China, there are many examples of using metaphorical connotations of irrelevant things.

The expressions of these clocks and watches have their own characteristics, but they are not completely separated when designing creativity. The comprehensive application of these methods is a common technique in logo design.

Logo is the product of synthesis and generalization, and it is the product of hybridization. Combining two unrelated graphs gives it new meaning and a new structure, and the reconstruction of this graph is synthesis and reconstruction.
