The scope of the manual is very large, not limited to a certain kind of people or a certain kind of content. No matter what age you are, you can choose to record what you want.
From the perspective of life, primary school students can also regard the handbook as a good-looking diary, or record ancient poems and excerpts. Reading, watching movies, traveling and other records are not limited to age, and you can record them if you have feelings. There is nothing to write in the notebook, only what you want to write.
