"Fa Tie Sanxi Hall" in Qing Dynasty, the engraving was rough, miscellaneous but not refined. Many of them are copied, far worse than the original.
"Spring Pavilion Post" was carved in the early years of the Northern Song Dynasty, and the carving was extremely fine. The value of the book in the Song Dynasty is closer to the original post because the Song Dynasty still retains a lot of ink in the Jin Dynasty.
Chunhua Pavilion Post is the earliest calligraphy post in China. In the third year of Song Chunhua (992), Emperor Taizong Zhao Xuan ordered the collection of Gu Mo in the Imperial Palace, and the calligrapher Hanlin compiled and copied the stele in the restricted area, naming it Chunhua Pavilion Post. This post, also known as "Fa Tie in the Secret Pavilion of Chunhua", is a 10-volume calligraphy and ink collection from pre-Qin to Sui and Tang Dynasties in China, including 420 works by emperors, courtiers and famous calligraphers. He was praised by later generations as the crown of Fa Tie in China and the "ancestor of Cong Tie".
