This is a calligraphy model called "Song Dynasty Rubbing of the Many Treasures Pagoda Stele," based on a Song Dynasty rubbing of the Many Treasures Pagoda Stele by Yan Zhenqing, a calligrapher of the Tang Dynasty. It is a rubbing of a stone inscription in regular script by Yan Zhenqing, a calligrapher of the Tang Dynasty. Its neat and powerful style is very famous as a basic model for learning regular script. The original stone inscription is currently housed in the Xi'an Beilin Museum in China. Thank you for viewing.
