Are Preface to Lanting Collection and Preface to Shengjiao Monument rubbings or ink?

Preface to Lanting Collection is ink, and Preface to Shengjiao is tablet extension. Preface to Lanting Collection is Wang Xizhi's calligraphy work, which is known as "the best running script in the world". Its artistic charm is self-evident, and the article itself is also a masterpiece. It comes from a direct imitation of the original, so the original Shen Feng is still there. Preface to the Holy Teaching is another calligraphy work of Wang Xizhi. Although it is a collection of words and a combination of missing words, its artistic value is still very high.
