Li Bai's Sai Shangqu skillfully uses contrast techniques, please analyze it briefly with poems.

the song of the plug

It snows in Tianshan Mountain in May, with no flowers but cold.

I smell the willow in the flute, but I haven't seen the spring scenery.

follow the golden drum at dawn and hug the jade saddle at night.

I'm willing to cut Loulan with my sword at my waist.

Translation

Snowflakes are still floating in the Tianshan Mountains in May, and there is only biting cold in the snow. The flute plays the tune of folding willows, and where to find the green spring of willows. Fight with the sound of golden drums during the day, sleep with a saddle at night, and only want to wave the sword at the waist to overcome the enemy.

Starting from "Tianshan Snow", point out "Stuffing Down" and write about the bitter cold on the edge. "May" is a hot summer in the mainland, but there is still "snow" in Tianshan Mountain. But the snow here is not flying snow, but snow. Although there are no snowflakes flying in the air ("no flowers"), I just feel chilly. There are still no flowers in midsummer and May, and it is conceivable how cold the rest three times (especially in winter) are. Therefore, these two sentences are light and heavy, and the words are vague and ambiguous. At the same time, the word "no flowers" is punning, but it doesn't mean flowers. This meaning is closely related to three sentences: "Smelling willows in the flute".
