The markings on the highway are important signs for regulating road traffic. Red is one of the common road marking colors and usually indicates a prohibition or warning. On the highway, our common red markings include no overtaking, no parking, no passing, etc. The setting of these markings helps ensure road safety and avoid traffic accidents.

Red is not only a sign of prohibition or warning, but also has other meanings. For example, in emergencies, red is often used to indicate when others are in need of help. Some people hang red flags on their cars or place them on their windows to indicate that the vehicle has been involved in an accident and call on other drivers to provide assistance. In this case, red shows people's rescue intentions and mutual help spirit.

In addition to its use in markings on highways and in emergencies, red also has important symbolic significance in life. In traditional culture, red represents enthusiasm, warmth and celebration. We often say "confidante", which illustrates the inseparable connection between red and friendship and love. In addition, red is also one of the main colors of the Chinese flag, representing the pride and honor of the Chinese people. The multiple meanings of red create different atmospheres and meanings for various occasions in our lives and work.
