During the class, the math teacher said that it is not environmentally friendly to burn paper after people die now. I am very happy that paper is not allowed to be burned now. I believe that my relatives can be self-reliant, and they will not let future generations burn paper for them in a hundred years. It is probably about the days of self-reliance after the death of a math teacher who was influenced by deep-rooted environmental protection concepts and materialism. The length of the full text is not necessarily certain. I am not good at math. I am learning and writing at the same time. If there are any math mistakes, please point them out.
Note: I don't mean to curse the math teacher. I like this math teacher very much. I just heard her say this and thought of writing such a plot. I also have no objection to the custom of burning paper to worship and do not interfere with other people's ideas.
Purpose: Protecting the environment is everyone's responsibility
