Should the text be written vertically from left to right or from right to left?

Write from left to right.

From the characteristics of Chinese characters and people's physiological habits, because the right hand is used to write and the left hand is used to hold the book, the stroke order of a character is naturally from top to bottom, from left to right.

If you write from right to left, when writing the left half, the brush will inevitably block the right half of the glyph, making it difficult to arrange the structure and affecting the beauty of the knot. The last stroke of each Chinese character is in the lower middle or lower right. The last stroke of the previous character is followed by the beginning of the next character. Vertical writing is more convenient than horizontal writing and makes the writing more coherent.

Extended information:

The reason why ancient people wrote from right to left is:

1. The ancients used bamboo slips, holding the pen in the right hand and unfolding the bamboo slips in the left hand. Of course It is written vertically and from right to left. In today's era, paper has been invented and writing on bamboo slips is no longer required. Therefore, there is no need to follow the ancient method of writing vertically, finishing one column, and then writing the second column to the right. It is more in line with modern people's habits.

2. Chinese characters are written from top to bottom, from right to left, which also reflects the ancients’ thinking of superiority and inferiority. In ancient times, the superiors were kings and parents; the subordinates were ministers and children. The right is big, the left is small, "nothing is better than the right" means there is no more.
