The environment is a global issue, and environmental pollution is a hot topic attracting much public attention and becoming increasingly serious. Through the media, we can easily see images and articles reflecting the current state of the environment. Although various departments and organizations are making efforts to protect the environment and water resources, all of this is not enough to improve the increasingly serious pollution situation. The drastic changes in the environment are causing many serious consequences for the lives, economy, and culture of each country. To live in a healthy environment, environmental protection awareness needs to be instilled in the younger generation.

The living environment has a positive influence on the formation of a person's character. In education, this is even more important because at school, children not only acquire knowledge and skills but also develop their character and life skills for the future. Building "A friendly school environment with active students" including construction "Green, Clean, Beautiful, and Safe School""The 'Green, Clean, Beautiful, and Safe' school environment has truly created a safe, enjoyable, and engaging learning and playing environment for students, helping them to become more attached to their school, teachers, and friends; allowing them to enjoy recreational space after stressful and tiring study hours. The 'Green, Clean, Beautiful, and Safe' school also has practical significance in educating students about environmental protection and fostering habits, creating a ripple effect in their families and communities. It contributes to shaping good character and a civilized lifestyle for the younger generation from their school years; and it engages families and society, playing a crucial role in the socialization of education."

With the aim of building a green, clean, beautiful, and safe school environment, Van Bao Primary School launched a classroom decoration campaign from its early years of establishment. This activity was enthusiastically participated in by the students. As a result, each classroom is fresh and colorful, making the students feel comfortable during each lesson.
