The regular scripts of Yan Zhenqing and Liu Gongquan were called "Yan Ti" and "Liu Ti" in history, and later generations passed down as "Yan Jin Liu Gu". They come from Fan Zhongyan's "Stone Sacrifice Scholars" and are called "Man Qing's". The pen is like the bones of the willows."
The facial structure adopts the ancient method of "eight points", taking the frontal position, so the posture is dignified, graceful, open and open, and the structure is uniform. The willow body construction method is based on the "two kings" and Beibei. Influenced by Ouyang Xun, the posture is taken from the side, and the "body posture is powerful and charming", which is steep and strange. The structure is rigorous, the rules are precise, the center of concentration is full of tension.
The brushes used in Yan style are steady and powerful, mostly in a round shape. When the stroke is started, the stroke is hidden and the stroke is drawn back. The momentum between the stipples is consistent. The horizontal strokes are mostly light, the vertical strokes are heavy, and the long horizontal strokes are closed with pauses. The pen is in the shape of "silkworm head and swallow tail". The twists and turns of Liu Ti's brush strokes, horizontal strokes, and strokes, as well as folding, turning, and thrusting are all in the same vein as Yan Ti's. However, in terms of brushwork, it is more willful and indulgent, with sharp edges and sharp edges in stipples and majestic squares and folds.
