There are similarities between running script and regular script. Take regular script as an example. In the picture below, the scarlet letter "Anti-Friendly Service under the Mansion" strokes upward at the last stroke, and the angle with the adjacent left or vertical is smaller at the top and bigger at the bottom; With horizontal skimming, the space formed is roughly triangular. In this way, the overall structure of the characters is compact, stable and symmetrical. Try to hold down the last pen, which will obviously cause loose structure. From the analysis, there are two kinds of such characters: 1, "Fu Bao" and other characters that are vertically adjacent to the last stroke (the most typical). 2. "Ba" is supported by the following words (some are slightly downward). The rest of the characters, such as "Mei Zhenglong's spiritual practice is handsome everywhere", such as the triangular space formed by the related painting is too upward and the other two paintings are too small, and the character structure appears cramped and unbalanced.
The same is true of running script, but it is handled flexibly from the overall aesthetic point of view because of the changes of related strokes. Please see the picture below:
