Emperor Taizong was an elegant calligrapher who loved Wang Xizhi's calligraphy. He once collected the original works of the two kings of the world to fill the imperial palace, and got the Preface to Lanting. He ordered Hong Wen Pavilion's extension calligraphers Feng Chengsu, Zhuge Zhen, Han Daozheng, Zhao Mo and others to fill in and copy the outline with double hooks and give it to kings and modern ministers of past dynasties. He also ordered Ou Yangxun to extend the Preface to Lanting to the final version. In addition, Yu Shinan also has a Preface to Lanting. And Li Shimin himself is also good at reading, learning from shaman. His books were listed as "exotic products" by Song people, and his book style was considered as "vigorous and elegant" and "the most exotic".
