What do you mean, I have you on the solstice in winter, and I don't sleep day and night, and lovesickness is not as good as long night?

There is you on the solstice of winter, and you don't give up day and night. When the weather is fine, acacia is not as good as night. The meaning is as follows:

In the solar term from winter to Sunday, the night becomes particularly long and the day is relatively short. However, even on such days, time seems to pass faster because you are around, and day and night seem to be intertwined.
