The whole article is about the word love. All feelings are like a big net, binding everyone in it. You can't struggle or throw it away. You can only endure it. Some people resist, but they lose their true heart and self. Some people endure silently, but they lose their feelings and become a walking dead. The most precious thing in the world is feelings, the most hurtful person is feelings, and the most helpless thing is feelings. Perhaps it is like that poem, asking what love is in the world, it teaches life and death.
