How do I look at signs as a designer

signs, as a special way of human intuitive contact, is not only ubiquitous in social activities and production activities, but also for the fundamental interests of the state, social groups and even individuals.
We generally divide signs into: special signs, public signs, traffic signs, safety signs, operation signs, etc., which have an intuitive and fast effect on guiding people to carry out orderly normal activities and ensure the safety of life and property.

Usually, when designing an sign scheme, we encounter the following situation:
1. According to the specific needs of customers, design signs that conform to the public aesthetic taste and have guiding functions;
2. The client will give us his original visual design system diagram as a reference and design a sign that conforms to the innovation in the visual system;
3. Under the premise that the customer has no idea or plan, we will guide the customer to design the sign that the customer needs;
4. For the design of the project scheme, we will design the sign scheme conforming to the standard through the requirements of the government's bidding documents;
