The Eight Principles of Yong (Chinese: 永字八法; pinyin: Yǒngzì Bā Fǎ; Japanese: 永字八法/えいじはっぽう, eiji happō; Korean: 영자팔법/永字八法, Yeongjapalbeop; Vietnamese: Vĩnh tự bát pháp) explain how to write eight common strokes in regular script which are found all in the one character, 永 (pinyin: yǒng, "forever", "permanence"). It was traditionally believed that the frequent practice of these principles as a beginning calligrapher could ensure beauty in one's writing.
The Eight Principles are influenced by the earlier Seven Powers (七勢) by Lady Wei Shuo (衛鑠) of Eastern Jin. Publications on the Principles include:
- The Praise to the Eight Principles of "Yong" (永字八法頌) by Liu Zongyuan (柳宗元) of the Tang Dynasty.
- Explanations to the Eight Principles of "Yong" (永字八法解) by Li Puguang (李溥光) of the Yuan Dynasty. Lǐ provided two-character metaphorical names.
