The '''Eight Principles of ''Yong''''' are used by calligraphers to practice how to write the eight most common [[Stroke (Chinese character)|stroke]]s in [[regular script]], using the fact that they are all present in the character {{zhi|c={{linktext|永}}|p=yǒng|l=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 calligraphy|Chinese calligrapher]]'s writing.

The Eight Principles are influenced by the [[Eastern Jin]]-era ''Seven Powers'' ({{zhi|c=七勢}}) by Lady [[Wei Shuo]]. Publications on the principles include:

===CJK strokes===
{{Main|Stroke (CJK character)}}
In addition to these eight common strokes in {{zhi|c=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 [[Chinese character description languages#Ideographic Description Sequences|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.<ref name="utf"/>
