In addition, in the process of writing, the consistency and rhythm of strokes are also very important. If you unconsciously leave some traces of pen tip movement after a stroke, it may affect the harmony and beauty of the whole word. Therefore, some calligraphers will put a hook at the end of the horizontal fold to eliminate this unnecessary trace and make the whole word look smoother and more natural.
In short, the second stroke of Japanese characters in calligraphy is crossed, not only for the sake of beauty, but also to make the structure of the whole character more harmonious and perfect.
