What's the color of a safety helmet?
Blue and yellow represent two different types of work, and they are all regular employees. The orange hat, in addition to the regular code, there are two English letters: WB, indicating outsourcing.
See the red hat carefully at a distance. Because red represents leadership. The leadership is fairly large. Up to the Prime Minister of the factory director, chief engineer, down to the small department of the security administrator, such as sesame green bean official, all red. Because this is not what China red red, pink, pink, so the light from the color is not resolved, but the "official" airs, domineering is just changed the color of the hat.
In large state-owned enterprises, the helmet can be described as a unique landscape. Different colors of helmets, on behalf of different identities, different types of work, different life.
