Canglang Pavilion was purchased by Su Shunqin for 40,000 coins.

Canglang Pavilion was originally the pool and pavilion of Sun Chengyou, the military governor of Zhongwu Army and a relative of Qian Yuanlu, the Prince of Guangling of Wuyue Kingdom during the Five Dynasties. Su Shunqin, a poet of the Song Dynasty, bought the abandoned garden for 40,000 coins and rebuilt it. He built a pavilion by the water and named it Canglang Pavilion after the poem "The water of Canglang is clear, and it can wash my tassel; the water of Canglang is muddy, and it can wash my feet." He called himself Canglang Weng and wrote "Canglang Pavilion Record." Ouyang Xiu was invited to write a long poem "Canglang Pavilion," in which he wrote "The breeze and the moon are priceless, but they are only sold for 40,000 coins." The couplet "The breeze and the moon are priceless, and the water and the mountains are full of love" is inscribed on Canglang Pavilion. This couplet was written by Liang Zhangju, a scholar of the Qing Dynasty, for Canglang Pavilion in Suzhou. The first line of the couplet is from Ouyang Xiu's poem "Canglang Pavilion," "The breeze and the moon are priceless, but they are only sold for 40,000 coins," and the second line is from Su Shunqin's poem "Passing by Suzhou," "The green willows and white egrets are all free, and the water and the mountains are full of love." It not only tells the story of the construction of Canglang Pavilion, but also describes the scenery of Canglang Pavilion, making people realize the concept of environmental protection that loves nature, conforms to nature, and is emotionally close to nature.
