Regular script is Ou Yangxun's masterpiece, which was written in the fifth year of Zhenguan in Tang Dynasty (AD 63 1).

Its "eight decisions" are: (points) such as the peak falling rocks; (Yoko) is like the new moon in the sky; (horizontal) like a thousand miles of clouds; (Vertical) Long live the withered vine; (Jiange) If Jinsong falls, it will fall on a cliff; (folded) like a crossbow of hosts; (left) If a sword breaks a rhinoceros horn; A wave of strokes is often repeated three times.
