The moon in the sea has tears, and the sun in Lantian is warm and jade produces smoke.
The first sentence of the neck couplet combines several allusions. Pearls are born from clams, and clams live in the sea. Whenever the moon is bright and the night is quiet, the clam opens to the moon to nourish its pearls, and the pearls get the moonlight. , began to shine brightly. This is a beautiful folk tradition. Tears are symbolized by beads, which has been the case since ancient times. When a shark weeps, the tears turn into beads, which is also a strange scene in the sea. In this way, the bright moon sets in the sea, and the pearl bathes in the boundary of tears. In the poet's writing, it has formed an indistinguishable wonderful scene. It is rare to see such a rich connotation and wonderful associations in one stroke.
The last sentence about the vast sea of ??Lantian is not groundless. Sikong Tu, a poet of the late Tang Dynasty, quoted a passage from Dai Shulun, who preceded him: "Poetry's beautiful scenery, such as the warm sun in Lantian and the smoke in good jade, can be expected but not placed in front of the eyebrows." The eight words used in this metaphor are , are exactly the same as the seven characters in the next sentence of this poem's neck couplet, which shows that this metaphor has another origin. Unfortunately, the ancient books were lost and it is difficult to find the source again. It is difficult to say whether the explanation given by Dai Dai is appropriate. Lu Ji, a writer of the Jin Dynasty, has a famous sentence in his "Wen Fu": "The mountains are shining with stone and jade, and the river is beautiful with pearls in the water." Lantian, the name of the mountain, is a famous jade-producing place in the southeast of Lantian, Shaanxi today. This mountain is illuminated by the sun, and the jade energy contained in it (the ancients believed that treasures have a kind of light energy that cannot be seen with ordinary eyesight) is slowly rising up. However, the essence of the beautiful jade appears to be there from a distance, but not up close, so it can be seen that It is impossible to look forward to it, which represents an extremely beautiful ideal scenery, but it cannot be grasped and cannot be approached.
