Only a few ancient calligraphers are recommended here.
Wang Xizhi: Preface to Lanting and Preface to Shengjiao (the two prefaces represent the pinnacle of Wang Xizhi's running script, among which Preface to Shengjiao is a collection of words and Preface to Lanting is a copy, which is known as the best running script in the world, and I personally think that Feng Chengsu's copy is the best).
Su Shi: Cold Food Post (the third running account in the world)
Mi Fei: Tiaoxi Poetry Post and Shusu Post.
Yan Zhenqing: The Draft of Sacrificing a Nephew (the second running book in the world)
Huang Tingjian: Song Fengge's Poetry
