The whole poem adopts the method of contrast. The first part describes the grand occasion of the Lantern Festival with bright lights and full of music, and the second part deliberately describes the protagonist looking for a lonely and tall woman standing in the scattered light among the good women. Delicate conception, delicate language, implicit euphemism and endless aftertaste.
From the tone of words, the jade case is unique. Originally, it was a double tone, with the same ascending and descending lines. Only the second sentence on the line became a broken sentence, with ups and downs. There is no such overlap in the lower altar. There are three sentences and seven words in one line, which can be arranged and changed, always according to the poet's meaning, but the trend of sentence arrangement is the same. The warning sentence can't be forced out until the parallelism is over.
