Say a ballad with the longest single cycle?

I just like listening to folk songs recently, and my favorite folk singer is Zhao Lei. The long-standing folk songs include Chengdu, Youth and Let me have a peek at you. One of my favorite songs is "Let me peek at you", which is a story-telling song, and its lyricist is a child. I fell in love with this song through the story in the big ice book. The story is called Children's Wish. Xiao Yueyang, the hero, is a particularly outstanding child and the pride of his parents since he was a child. When he was in junior high school, he wrote many songs. He said that he would give them music after learning music. But then he died of leukemia at the age of fifteen. Because my mother once said, "If you die, your mother will not live." In order to make your parents live strong, he left a wish before he died, so that his parents could bring these songs to Dabing and let Dabing's folk singer friends give them music. Da Bing later discovered a passage he had written before his death. He said that when mom and dad fulfilled his wish, they would get out of the pain, so they wouldn't want to die with me. So every time I hear this song, I think of him. "Let me peek at you/in the breeze you look back at/in the back of your departure" is a beautiful lyric written by a teenager. His wish is so capricious, but his purpose is so touching.

The first song that Zhao Lei listened to me was "Let me peek at you". He is also a folk singer with a great story. He once opened a bar in Lhasa with Da Bing, and once wandered and sang. But I like listening to Zhao Lei's songs, because his voice is very low. Listening to his songs sometimes feels very cordial, and the singer is his old friend.
