Walking through this reed slope, have you ever heard of a girl who left a song? Why clouds, quiet tears, why gusts of wind, whisper. Hi. hi. There are a group of red-crowned cranes flying by gently and gently. My friends of the same age must remember this song of Zhu Zheqin when she was a child, in memory of a girl named Xu Xiujuan in Zhalong Nature Reserve, who gave her young life to protect the red-crowned cranes. At this moment, I stand on this vast black land, the familiar song of childhood floats in the wind, the dark blue sky is clean without a trace of cloud, the golden reed is far from the end, the white red-crowned crane is like an elegant and lonely gentleman standing in the clear lake water, totally ignoring the peeping eyes of human beings around. Others have used life to write this beautiful picture, but also let me deeply, deeply engraved in my memory.
