Introduction to Xishan No. 1 Square: Zhu Xi, a great Neo-Confucian scholar and poet of the Southern Song Dynasty, visited Chen Fuliang and "kneaded" Neo-Confucianism with Chen Fuliang. He left an inscription with the eight-character golden saying "Xishan No. 1" and "opening the sky". Well, later generations built a square to commemorate the original site of "Xishan No. 1", and also used this square as the gate of Xianyan Mountain. There is an exquisite couplet in the original square: Qingshan is a national treasure, and nine lions surround the immortal rock. It was a pity that it was destroyed during the Cultural Revolution. The current square was moved and built, which is larger than the original square and has four pairs.
