The national treasure that is quietly guarded is "Long Live Tian Tong Post", also called "Tang Shu Wang Xizhi Wang Zhang Bao Collection". In the Song Dynasty, the Secret Pavilion continued to be posted, and in the Ming Dynasty, the Shang Zhen Pavilion of Huaxia, the Ting Yun Pavilion of Wen Zhiming, the Yugang Pavilion of Wang Kentang and the Fa Tie of Sanxi Hall in the Qing Dynasty were burned. Among them, it is famous for its exquisite carving.
It is said that Wu Zetian loves calligraphy. She summoned Wang Fangqing, the tenth generation grandson of Wang Xizhi, and asked him to contribute all the calligraphy relics of his ancestors. Of course, Wang had no choice but to present them, so Wu Zetian asked the workers to copy and save them. Because Wang Xianzu's signature is "Long live the sky" next year (Wu Zetian's title is very unique, right), so history calls this post "Long live the sky".
Tian Tong Post in Tang Dynasty was more important than Yuan Huan Post in Taiwan Province, Confucius Post and Japanese Funeral Post. With its loyalty to the original work, it provides a reliable basis for people to study the calligraphy of the two kings and the Eastern Jin Dynasty to the Six Dynasties. Long live the Tian Tong Post contains profound historical and artistic values.
