1. Regarding the writing direction of the ancients, we have to mention bamboo slips.
In ancient times, writing appeared much earlier than paper. At that time, people could only write on animal bones, containers and bamboo slips. The ancients accepted bamboo slips more easily in terms of production cost and portability. Seeing bamboo slips, we can easily understand the direction habits of ancient people's writing. The ancients used to go from right to left and from top to bottom.
Bamboo slips are tied with bamboo strips. In the process of writing, people are always used to writing with their right hand. At the same time, when the volume is turned on, it is also held in the right hand and unfolded in the left hand, which looks very convenient. The reason for operating in this direction is that people used brushes and ink at that time. In order to ensure that the handwriting can be dried thoroughly before the bamboo slips are folded, it is natural to write the right part first and then the left part. So the ancients naturally formed the habit of writing from right to left.
2. The ancients' strict concept of respect and inferiority respected dragons.
During the period of bamboo slips, people have solidified the habit of writing from right to left. So after the appearance of paper, people still kept this habit. In the subconscious of the ancients, they thought the right side was the noblest. This is why the ancients wrote Chinese characters from top to bottom and from right to left, which also reflected that the ancients attached great importance to the concept of inferiority.
Cultural diversity makes it more convenient for people to choose from left to right.
After the Revolution of 1911, learning from the characteristics of western culture, China began to connect with the world. Many new cultures and new weather have been introduced into China imperceptibly, which set off a trend at that time. Many people in new cultures responded positively and gradually changed the order and way of writing Chinese characters.
To sum up, the change of China's writing style is also a manifestation of cultural progress, and it is best to conform to the society.
