The so-called calligraphy post is to engrave the ink of the famous ancient calligrapher on a slate or a wooden board after being traced by a double hook, and then print and bind it into a post.

Let's look at two law posts:

1, 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 scribe Hanlin compiled and copied the stele in the restricted area, named "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".

2. Sanxitang, Fa Tie, a block print of the Qing Dynasty in China. Carved in the 12th year of Qianlong (1747). Ming Taizu ordered Shang Shuliang, Shang Jiangpu and others in the official department to select the essence from the calligraphy works collected in the imperial palace in the past dynasties, which were carved by, Koukou and Jiao Lin respectively. Calligraphy posts are divided into 32 volumes, with more than 500 carved stones, and more than 300 calligraphy works by 35 calligraphers from Wei, Jin and late Ming dynasties/KLOC-0 have been collected. Because there were three rare books in the Eastern Jin Dynasty, which were regarded as Mo Bao by Emperor Qianlong at that time, namely Wang Xizhi's Quick Snow Clear Post, Wang Xianzhi's Mid-Autumn Post and Xie Wang's. Fa Tie's original stone is embedded in the wall of Beijing Beihai Park Drum Tower.

Therefore, I personally think that each has its own merits, and different people have different opinions.

I don't know. Are you satisfied?
