The earliest bookshelves can be traced back to the ancient library in Ebra, an ancient country in Syria. It is located in the northwest of Syria today, not far from Aleppo. The wooden bookshelves there are placed in a small library, only 5.5 meters long and 4 meters wide. At that time, the clay tablets on the bookshelves were not placed outward with the spine (because the clay tablets had no spine), and the "cover" with words written on it was lined up in front of the readers, so the distance between the bookshelves was very loose, and the readers could go around the back of it. There are some small clay tablets hanging at both ends of the bookshelf to classify the clay tablets; In the 6th century A.D., Fu Kun, a carpenter from China, invented the wheel storage, that is, the rotatable bookshelf of Buddhist scriptures in Buddhist temples. It is said that Fu Kun believes that a devout person can gain enlightenment, lessons and understanding by touching the wheel with three Tibetan scriptures and turning it, and the effect is the same as reading all the scriptures. After that, this concept spread all over China and Japan, and the scale of Tibetan ships became larger and larger, and the distance between people and classics became farther and farther. In the Mitsui Temple in Japan in the15th century, there was a huge rotating wheel, and the inner space of the temple was almost completely occupied by this huge octagonal bookshelf, which was full of Buddhist scriptures from bottom to top. At this time, the scriptures themselves become sacred, and the "reading" bookshelf simply means turning over.
