The positioning of city brand needs to explore the core value of the city through investigation, analysis and evaluation, and realize differentiation and personalization. The design of urban signs should strengthen and highlight this difference, and transform it into urban visual symbols through generalization, refinement and abstract design.

2. A slogan that conforms to the image of the city

City image slogans are often launched at the same time as city image signs. The slogan of city image expresses the positioning and development concept of city brand in words, which is more direct than the graphic symbols of city signs. The city image logo fits well with the city image slogan, which can vividly spread the city's core values and spiritual concepts, and the city image slogan becomes a part of the interpretation of the city logo.

3. Extraction of urban characteristic elements in logo design

Logo is a sketch in art design, which has the modeling characteristics of seeing the big from the small and winning more with less. Logo graphics are more concentrated, more intense and more representative than other artistic styles, which are highlighted in the visualization of artistic generalization. Their characteristics are concise and clear, as clear as symbols. In the design of city signs, we should look for symbols of urban characteristic elements and express the characteristics of the city with perceptible image elements.

According to the scale, characteristics and highlights of the city, simplify the design and integrate into the concept of urban development.
