Why did the ancients write vertically?

We often see the ancients in TV dramas. They write vertically. It can be said that their strokes are not horizontal. Why do they like to write vertically? In fact, it has a lot to do with the conditions at that time.

There was no paper-making technology in ancient times. They write on bamboo tubes. Make bamboo piece by piece, and make him some brochures with some thin lines. After editing, you can write on the bamboo tube. They write vertically. If they write horizontally, the bamboo area in that booklet will not be so big. This booklet needs bamboo at the same time. In order not to disturb the order, they are all written from left to right.

Our Chinese characters are written from left to right, as well as our writing habits. The stroke order of a word is naturally from top to bottom, and it will be more convenient from left to right. If you write horizontally from right to left, when you write the left half, the brush will block the font in the right half, and the poor arrangement will also affect the beauty of the words. Basically, the last stroke of Chinese characters is in the middle or lower right. After writing the last stroke of the last word, I feel that writing vertically is more convenient for the continuity of strokes than writing horizontally.

It also has a lot to do with the concept of the ancients. In ancient times, ancient people were very obedient. They think justice is the noblest. In ancient society, they obeyed the rules, and if they didn't, they would be punished. Therefore, the ancients wrote from left to right and from top to bottom.

There were no books in ancient times, and many people carved words on stones. They all hold a pole in their left hand and a hammer in their right. So their lettering direction is from left to right, so they all write vertically, not horizontally.
