By standardizing the appearance and logo of clean energy sanitation vehicles, we will achieve unified standards and unified appearance, and create a highly recognizable new business card for urban environ- mental protection. Create a set of super symbolic graphic expressions highlighting environmental protection, cleanliness, energy saving, I love Shenzhen, etc. from elements such as sunshine, rain and dew, bougainvillea, air, green leaves, recycling, etc., and create an environ- mentally friendly symbolic public identification image system with Shenzhen characteristics. The entire plan is modern, stylish, simple and elegant, and is very easy to implement and promote in a standard- ized manner. It not only respects the practical functions of the sanita- tion industry, but also reflects the unique charm of Shenzhen.
