Next to the West Warm Pavilion in hall of mental cultivation, there is a small house of several square meters, and Qianlong named him "Sanxitang"
Because he often plays with his three favorite calligraphy masterpieces here, he got the name.
Three wishes, one is Wang Xizhi's "Quick Snow Clear Post", the other is Wang Xianzhi's "Mid-Autumn Post" and the other is Wang Xun's "Yuan Bo Post".
These three treasures have been loved and played all their lives.
The name of Sanxi also contains the meaning of Zhou Dunru's "wisdom, wisdom and sage, and wisdom", which inspires him to keep forging ahead, improve his self-cultivation and enter a higher realm.
