The meaning of the whole poem: searching hard, only to find that it is deserted, how can it not make people sad. It is the most difficult to maintain and rest when it is warm and cold. How to resist the cold wind in the morning after drinking three or two glasses of light wine? A line of geese flew in front of us, which was even more sad, because they were old acquaintances. The chrysanthemums in the garden are piled all over the floor, and they are already very haggard. Who else will pick them now? How can you stay up until dark alone and watch the window coldly? The plane tree leaves are dripping, and it is still dripping at dusk. How can such a scene end with a word "sadness"?
