The poem Night in the South describes such a picture. The stars are shining, reflecting the green lake, and a pair of lovers are sitting next to each other by the lake on a summer night in the north, talking softly. In the early summer night in the north, although the wind is no longer raging and the wind is biting, it still gives people a cool feeling. However, what the poet feels is that the reeds at night are evaporating with strong passion, and the swallows are dancing happily with the stars on the lake. The same scenery has different feelings in different people's hearts, reflecting two people's different moods, and the environment is born from the heart. It is not difficult to find the profound meaning. Although the other party felt the silence of autumn, the poet still wanted to use the swallow returning from the south as a messenger to awaken her cold impression. The intoxication of the southern night is the poet's intoxication of love, but this intoxication did not get the same degree of * * * feeling on the other side. This poem "Hot and Cold" appropriately shows the contradiction that men and women in love feel unsynchronized about love, so the poet urgently wants to let his lover enter the same spiritual realm as himself with warm smells, sights and sounds.
