In the poem Dai Tian's Visit to a Taoist priest, the word "neck couplet" is well used.

"Wild bamboo is green and misty, flying springs hang blue peaks" is the poet's third trip into the mountains. From the last couplet "Don't smell the bells", we can imagine that the poet is still a long way from the Taoist temple. This couplet describes what I saw when I came to the front of the Taoist temple-the Taoist priest was not there, and I only saw the green bamboo mixed with green mountains and the waterfall hanging on the Bifeng. The poet's pen is ingenious and delicate: the sentence of "wild bamboo" uses a word "fen" to describe two similar tones of wild bamboo and green fog, forming a piece of green; The "flying spring" sentence uses the word "hanging", which means that the white flying spring and the blue mountain peak set each other off. Obviously, due to the absence of the Taoist priest, the poet was bored, so he looked around and savored the scenery in front of him. Therefore, these two sentences can not only show the indifference and nobleness of the pure land of Taoist temple, but also understand the poet's feelings of not meeting each other when he visits.
