Yan Zhenqing's regular script embodies a prosperous style and momentum; Liu Gongquan studied under Yan Zhenqing, and absorbed his new ideas, which made his ci avoid the trend of horizontal fine and vertical, took even fine and hard, and chased Wei Bei steadily, with beautiful stippling, strong bones and tight structure. Many scholars in later generations took Liu Zi as a model.
Liu Gongquan's regular script involves Ou Yangxun's brushwork, and some strokes are often closely interspersed, which is particularly broad, fine and angular. Although the pen was written by Yan Zhenqing, it is different from Yan Zhenqing's vigorous and broad style, which is particularly heroic.
