Written by professor Long-Min She. Font writing aims to master the beauty of calligraphy. The principle of the strokes is to be smooth and vivid; as for the structure, in order to achieve beautiful typesetting and printing, try to maintain a “dignified” posture. The “reduplication” function was added to AR DCYKxingkai; when he was writing, he purposely created “different writing for the same word” to show the beauty of “not the same” and “not repeating” in calligraphy, allowing AR DCYKxingkai to better display the spirit of calligraphy art. Also, two different calligraphy styles are provided for AR DCYKxingkai, in which the AR DCYKxingkai inscription version used different methods such as shared radical, changed writing and increased/reduced strokes to preserve the beauty of traditional calligraphy brush art.
