2. The stroke of eyeball moving up and down is shorter than that of eyeball moving left and right. If the planning is reasonable, vertical rows with the same length are less likely to be dislocated than horizontal rows.
3. Chinese characters were originally developed in vertical form, from the rectangular structure of Xiao Zhuan to the flattening of strokes in official script, and then to the removal of regular script, all under the framework of vertical version.
Therefore, the pace of Chinese characters is generally balanced up and down, with more horizontal mechanisms at the bottom and more "thorns" in vertical strokes to support the whole character; This kind of vertical ridge is easy to form a set of hidden trend lines when it is arranged vertically, but this trend is not easy to be reflected when it is arranged horizontally. 4. This should be a shortcoming of the vertical version ... The same length, the vertical version is longer than the horizontal version, and it is easy to jump. And because of the length of the line, frequent line breaks are easier to waste paper space than horizontal lines ... but this can be overcome by column separation.
