永字八法

Eight Principles of Yong

Demonstration of CJK character strokes

永字八法，是古代书法家练习楷书的运笔技法。“永”字有八笔：点、横、竖、钩、挑（或提）、弯、撇、捺，按各自的笔势以八字概括为侧、勒、弩（又作努）、趯（tì）、策、掠、啄、磔（zhé）。这八笔是楷书基本笔画，每笔各有特色，而又互相呼应，一气呵成。如李溥光《雪庵八法》称：“磔法之妙，在险横三过，而开揭其势力。”如果能写出“永”字每笔的精神，楷书可算达到相当水准。

历史

“永”字八法的来源，有一说是出自东晋的王羲之，另说是崔子玉、钟繇、智永、张旭。

八法的出现，深受《笔阵图》所总结汉字七条“笔阵”（七势，包括：横、点、撇、折、竖、捺、钩）所影响。据称《笔阵图》为东晋卫铄（卫夫人）所著。此外，不同时期的书法家也有相关技法的描述，例如：

《永字八法颂》颜真卿（唐朝）

《永字八法颂》柳宗元（唐朝）

《永字八法解》李溥光（元朝），他使用了二字象征意象命名各笔画。

英文维基百科补充中文条目比较短，下面是英文条目「Eight Principles of Yong」的原文

The Eight Principles of Yong are used by calligraphers to practice how to write the eight most common strokes in regular script, using the fact that they are all present in the character 永; yǒng; ''forever'', ''permanence''. It was believed that the frequent practice of these principles as such when beginning one's study could ensure beauty in the Chinese calligrapher's writing.

The Eight Principles are influenced by the Eastern Jin-era Seven Powers (七勢) by Lady Wei Shuo. Publications on the principles include:

The Tang-era Praise to the Eight Principles of "Yong" (永字八法頌) by Liu Zongyuan

The Tang-era Praise to the Eight Principles of "Yong" (永字八法頌) by Yan Zhenqing

The Yuan-era Eight Ways to Explain "Yong" (永字八法解) by Li Puguang, which provides two-character metaphorical names

CJK strokes

In addition to these eight common strokes in 永, there are at least two dozen strokes of combinations which enter in the composition of CJK strokes and by inclusion the CJK characters themselves. Most strokes are encoded in Unicode as symbols, to be used in ideographic description sequences (IDS). The standard characters names assigned in the UCS for these CJK strokes are based on initials of the modern Chinese names (romanized with Pinyin) of component principles with which they are recognized and drawn.
