The price of calligraphy works rewarded by Heaven.

The specific value of calligraphy written by different calligraphers is different. For example, you can enjoy two calligraphy works that reward diligence in heaven displayed in Yi Cong:

The picture shows the calligraphy of Guan Shan, the calligrapher of the State Guest Ceremony.

This picture shows Li Chuanbo, a disciple of Qigong, rewarding hard work in Qigong calligraphy.

Although the contents of the above two pictures are the same as the scale, the specific values are somewhat different.
