1. Wang Xizhi’s calligraphy became famous all over the world when he was forty years old. All his writings were cherished by the world during his lifetime and were collected by people, including emperors of all dynasties. They relied on their rights and wealth to purchase a large number of Wang Xizhi's works from the public. For example, Emperor Ming of the Liu Song Dynasty, Emperor Wu of the Liang Dynasty during the Southern and Northern Dynasties, and Emperor Taizong of the Tang Dynasty were the three emperors who purchased the most royal books in history, and they collected thousands of royal books. However, the admiration and private collection of Wang Xizhi's writings by emperors of all dynasties led to the massive and concentrated destruction and loss of Wang Xizhi's authentic works, which became an important reason for the loss of Wang Xizhi's writings in addition to the successive wars and disasters in the turbulent years.
2. At the end of the Eastern Jin Dynasty, when Huan Xuan was defeated and fled, he threw all his treasured royal books into the river; Emperor Wu of Liang Xiao Yan collected a large number of royal books in Liang Neifu. After the fall of Jiangling, At that time, Emperor Yuan of Liang burned the collection, and the Northern Zhou general Yu Jin "picked up the lost items", but was unable to recover them. This was also the most serious destruction of the King's Book in history. Emperor Yang of the Sui Dynasty was also fond of the king's books, and he never forgot to take the king's books on board the ship to read them when he was on tour. Unfortunately, the ship sank and all the treasures he carried were lost.
3. Emperor Taizong of the Tang Dynasty loved the character Wang very much. He only respected Wang Xizhi's calligraphy and took various measures to establish Wang Xizhi's status as the "Supreme Calligraphy". He ordered the collection of a large number of royal books, and the authentic copy of the peerless calligraphy "Lanting Preface" was also used as a burial object after the death of Emperor Taizong of the Tang Dynasty, "following the immortals into the Xuan Palace". During the Anshi Rebellion that followed, most of the large number of royal books collected in the Tang Dynasty's inner palaces were "abandoned."
