What is Wang Xizhi's calligraphy work Preface to Lanting Collection?

The original is a running script stone tablet, most of which are inscriptions! Later generations have copied works, cursive script, regular script, cursive script and so on!

I bought two books in Xinhua Bookstore last week, including two volumes. You can pay attention to them when you have the opportunity. The books are all marked "Wang Xizhi's running script" and so on!
