Calligraphy is nothing more than brushwork, structure, style and composition.
Personally, I think that when writing, the strokes are dignified, and some strokes pursue late convergence, and the starting, closing and turning points are not natural and smooth enough, and there is no echo. The structure of individual words is also lacking, which is too dull and affects the overall composition.
For these reasons, the whole article has a slow rhythm and a bad breath. It gives people an intermittent feeling in rhythm.
