Good habit of saving
Not long ago, my uncle taught us about the concept of saving. Recently, we found that everyone has begun to consciously reduce waste. Now, we understand that there is no need to waste a lot of resources when a small amount of resources are enough to complete the task. In the past, a roll of paper might only be used up in two weeks, but now with a sense of conservation, a roll of paper might take three weeks or even longer to be used up. This awareness will also be reflected in many other places. Usually when everyone encounters something that is not necessary to waste, everyone will remind each other.
And you must not only cherish your own things, but regard everything as your own. When you can save, never waste.
