Zhao Mengfu's words mean that no matter whether you write Wang or seal Kai Lee, the brushwork it uses remains unchanged from ancient times to the present. Calligraphy is the most important basic skill in calligraphy learning, and it is also an important basis for judging the level and elegance of calligraphy.
"Horizontal" is the most used stroke in Chinese characters. What strokes does Xiao Heng contain? The following knight-errant will give you a detailed explanation (taking Ou Kai as an example):
1 contains three strokes: cut, lift and turn.
The central stroke is smooth and stretched, and the outline outlined by Qi Li is solid and powerful.
3 close the pen, lift the nib to the upper right, use the nib to the lower right, and finally return to the front to close the pen.
Of course, many calligraphers do not follow the above steps, because they have reached a comprehensive level of brushwork. But as a beginner, only by receiving strict and standardized brushwork training can we achieve "the book is better without Yoga Yu's meaning".
