Introduction to the Baishan Screen Wall: The Baishan Screen Wall was built in the Daoguang period of the Qing Dynasty. All the shapes of the "good" characters are ancient and modern, and each has its own unique style. They are all written by calligraphers from the Shang, Zhou, Qin, Han, Jin, Southern and Northern Dynasties, Sui, Tang, Song, Yuan, Ming and Qing dynasties. The 365 good characters are a warning to future generations to do good every day for 365 days in order to accumulate virtue. .
