I think the books on the shelf should be classified and put together according to the nature of the books, which will be very convenient to find. However, most people usually make trouble in the future for temporary convenience. In fact, I think each layer of the bookshelf may need to put different types of books. For example, I will make a classification on my bookshelf, and the nature of the books on each bookshelf is different.

I think the so-called neat arrangement is not just vertical or horizontal. I think the two ways can be combined, and usually this way can look more tidy.

Mainly according to the nature and labeling, the types of books placed on the first floor are posted on the shelves on the first floor.

Perhaps this arrangement is clearer and neater. Books on the first floor can be placed vertically, and books on the second floor can be placed horizontally. In fact, this is mainly the size of the reading shelf, so it is good to make maximum use of the bookshelf.

It is very simple to arrange the bookshelves neatly.

First of all, it is more detailed that you can't fold every page of the book, and you can't fold it all in the lower right corner, which will inevitably appear messy. Besides, you can't put too many things in each book. If you put too much paper, the book itself is already bulging. How can you put it neatly in the bookshelf?

If you put all the books in order and there is not too much paper in the book, then the book will look very neat and heavy.

Then it is necessary to put the book on the shelf. As we all know, if you don't put the books on the bookshelf according to their thickness or height, it will inevitably appear very messy and uneven.

Therefore, if you want to arrange the bookshelves neatly, you should put the books in a certain order, such as from high to low, and only from high to low will these books appear orderly.
