This poem expresses deep feelings of missing. Through the image and vivid description of "inextricably linked", it shows the intricate and complicated emotional entanglements between people, and emphasizes the strong feelings of caring and missing in people's hearts. When we have feelings for someone very much, that kind of care and yearning will turn into countless tears, which makes it difficult for us to give up.
And the phrase "turning into missing and sending homesickness" expresses that people turn this feeling of missing into an action, that is, thinking attentively and explaining their missing with actions. In this era of information explosion, in order to convey their thoughts to people far away, people now use various scientific and technological means, such as text messages, telephone calls and emails, to express their thoughts and care for each other.
