The poem about kissing the other person without getting a response is like the falling flowers deliberately followed by the flowing water, but the flowing water has a ruthless love for the falling flowers. When the other party does not respond to the poem, seeing is not seeing. Seeing is still far away from seeing, seeing is out of reach. Falling flowers follow the flowing water deliberately, but flowing water ruthlessly loves falling flowers. From the "Continued Record of Deng Zhuan: Zen Master Shigui of Longxiang Zhu'an in Wenzhou". It is often used to describe the love between a man and a woman, where one party is intentional while the other party is ruthless.
