1, "How can you be heartless if you don't see each other?" Sima Guang's "Xijiang River, Bao Yue, Song Ji and Song Wan Nine" in the Song Dynasty interprets this as saying that this sentence expresses a sense of powerlessness that cannot change or solve a certain situation.
2. "When I turned to see my little daughter, tears ran down her cheeks." From "Seeing Yang's Daughter"
The explanation is that this sentence expresses a father's powerlessness in the face of his daughter's departure. In his poems, Wei described that when he came home, he saw a lonely little girl with sad tears rolling along his hat belt, which showed his helplessness and pain that he could not change this reality.
3, only send spring home, send you home. If you go to the south, you can catch up with spring, and you must keep the scenery of spring. From "Buji sends Bao Haoran to East Zhejiang", this sentence expresses the feeling of powerlessness in seeing friends off. Wang Guan described in his ci that he had just sent away the spring and sent his friends home, showing his helplessness and regret that he could not stay.
