What are the advantages of arranging Chinese characters vertically, from right to left?

From the perspective of visual communication, writing horizontally from top left to bottom right conforms to the law of rapid reading of human brain. In the era of modern knowledge explosion, we can master more knowledge faster by reading, and writing vertically from the top right to the bottom left is because there are not so many books that ancient people need to read, and the core is a few books such as the Four Books and the Five Classics, which need deep memory and constant understanding. Words are written from left to right in the main order. First of all, Oracle Bone Inscriptions on Oracle bones was a divination with a special purpose at that time, not a formal writing, and some Oracle Bone Inscriptions wrote from left to right. Vertical writing is limited by the material of bamboo. In fact, it is generally believed that bamboo slips were the main tool for writing the earliest characters, but the ancestors of the Yin Dynasty had books and codes. Unfortunately, Shangshu Toz is not easy to save. The arrangement from right to left, as one of the answers said, is related to the bamboo slips held in the left hand. As for the way of reading is in line with human physiological structure, it must be more in line with horizontal reading. The evidence is that the reason of eye muscle structure is that most people who write are right-handed, so it is the most convenient. Every line of characters is written from top to bottom, and the origin of this social habit is roughly related to the making of bamboo slips, the fiber texture of the carrier and the convenience of writing. Writing between the lines, from right to left, is a social habit brought about by specific cultural factors, but it is not directly related to sleeves and the like. From the point of view that ancient paintings involve writing, there are the following reasons: when recording literature files in real time, such as the records of historians and students, bamboo slips are compiled in advance and can be compared with current notebooks. When recording, because the right hand holds the bamboo slips, the right hand writes, the left hand rolls up the unwritten part of the bamboo slips, finishes writing a bamboo slip, and introduces the left bamboo slips in turn.
