There is a poem about cactus as follows:
"Zhongfu, the nephew of the tribe, presented cactus tea from Yuquan Mountain" Li Bai (Tang Dynasty): When exposed, it becomes a cactus, like patting the shoulder of a Hong cliff. Interpretation: Look at the tea leaves that have been exposed to the sun and look like a cactus, as if you could use it to pat the Immortal Hongya’s shoulder.
"Walking Through Huayin" Cui Hao (Tang Dynasty): The clouds in front of Emperor Wu's temple are about to disperse, and the rain has begun to clear on the cactus. Interpretation: When the poet was passing through Huayin, it was just after the rain and the sky was clear. He looked at the smoke and clouds gathering in front of the Emperor Wu Temple and was about to disperse; looking up at the Cactus Peak, the mountain shape has become eye-catching and naturally beautiful. New sunshine and new bathing, the scenery is charming.
"Water Dragon Odes White Lotus" Zhang Yan (Song Dynasty): The hibiscus on the cactus is like a wet gold plate with dew. Interpretation: You are like a hibiscus on a cactus, like you are in a copper dew tray. The water dripping from the flower is like crystal jade dew.
"Two Songs for Playing with Friends" by Li Shangyin (Tang Dynasty): The dew of the cactus is cold for three days, and the window of the jade girl is filled with cold wind for five nights. Interpretation: The copper plate on the cactus is full of dew; the jade girl's window is open, and the night air is cold.
Extended information
"Water Dragon Song·White Lotus"
The hibiscus on the cactus is like a wet gold plate with dew. With light makeup and shining in the water, her slender clothes are standing upright and fluttering like a dance. The condensation has disappeared several times, and the lake is full of smoke and moon, and there is a gull and heron.
Translation: You are like a hibiscus on a cactus, like you are in a copper dew tray. The water dripping from the flower is like crystal jade dew. The elegant makeup and the lake water reflect each other, you stand tall and graceful, and the hazy moonlight covers you with thin clothes.
The breeze blows and you are dancing. In order to catch a glimpse of your beauty, I wandered and gazed. I have been here several times, intoxicated by the mist and moon shrouding the lake.
