There are only two lines in the poem, but it attracts people's attention because of two special images: "ghost" and "branches and petals". Paris, Place de la Concorde, subway station exit, among the dense crowd, poets are among them, pedestrians rush in and pass by, the light is not good, and the weather is cold and humid. Suddenly, a beautiful face flashed, then another, then a child's face, then a beautiful woman's face ... in the dim crowd, they stood out.
The poet described such a moment with two juxtaposed images, which were intense in color, mysterious and beautiful. At this moment, the world had to stop in a hurry because of the poet's peculiar talent.
