If you say there is a strange fate, how does your mind eventually become empty? What are these words from China's classic works?

This sentence is taken from the fifth time in A Dream of Red Mansions. The original sentence is: you said that there is no strange fate, and you will meet him in this life. If you say you have a strange fate, how can your mind be empty? It means, if there is no magical marriage, why did you meet him in this life? If there is a magical marriage, why does full love finally become an empty talk?

The author also turned this sentence into a poem, one is Xianpa in Yuen Long, and the other is immaculate jade. If there is no strange fate, I will meet him again in my life. If there is a strange fate, how can my heart eventually become empty? One is futile, and the other is alarmist. The poets expressed their helplessness and contradiction by asking questions. The last sentence expressed Jia Baoyu's deep affection for Lin Daiyu, and his tears kept breaking his heart.
