Youth, Youth is a song written by Liang Mang, composed by Yang Fei and sung by Zhou Xiaoou. Part of the lyrics of this song is: Like a river, winding and sad, when you wake up, the water flows through Sanqiu. I haven't heard yesterday's dust for a long time when the breeze blows away. Your singing, youth, looking for a needle in the sea, I stood on tiptoe to dance, so naive.
