The mystery of Wang Xizhi's original work

Today's so-called Wang Xizhi, handed down from Mo Bao or handed down from generation to generation, is a copy of the Tang Dynasty and the Song Dynasty. For example, Wang Xizhi's Preface to the Lanting Pavilion in Tang Dynasty has eight kinds of manuscripts, among which Feng Chengsu's manuscript is the closest to Wang Xizhi's original work, and Ou Yangxun's Dingwu Linben is a kind of catching up with Wang Xizhi's charm. Generally speaking, as long as the copies of the Tang people are passed down in an orderly way (such as the first moon stickers, the stickers for mourning the past, the stickers in the sun in the snow, etc.), they are close to the original. ). On the contrary, it may have been invented by calligraphy masters who studied Wang Xizhi at that time. In the Song Dynasty, under the influence of Song Huizong, the atmosphere of learning calligraphy rose sharply. There are many fine engravings of Wang Xizhi's calligraphy (such as Huang Tingjing, Dong Fangshuo's paintings and Zhong You's thousand words).

Which tomb of Emperor Taizong, Emperor Gaozong and Wu Zetian did Wang Xizhi's Preface to Lanting enter? It needs later archaeological excavation to confirm.
