Although there are many books and works of art in the Preface to the Lanting Pavilion, according to scientific analysis, whether it is placed in a famous museum or in the hands of treasure collectors, it is not the original work of Wang Xizhi. Long, long ago, Wang Xizhi was chatting with friends in Yin Lan Ge, and suddenly he had inspiration, so this book came from this. Later, Wang Xizhi returned to China and wrote several times, but he didn't write anything more satisfactory than this. So it became Wang Xizhi's treasure and passed it on to future generations. The book reached the hands of his seventh generation of descendants and then spread to foreigners. He was once a disciple of Sun Zhiyong, a monk, but his eloquence has been carefully preserved, but no matter how careful he is, he can't compare with unscrupulous people. Emperor Taizong was also a calligraphy lover. So people like him who want what they want will definitely try their best to get it. Therefore, after receiving the order from Emperor Taizong, Xiao Yi went to get the original handicraft of Preface to Lanting, so it finally fell into the hands of Emperor Taizong.
According to the records of ancient history, after the death of Emperor Taizong, the Preface to Lanting was buried with Zhaoling, so no one opened it today, so naturally no one has seen this original work since Emperor Taizong, so the best work now is the one that was copied. However, we only speculate on the origin of this book according to historical records.
