The composer of 'Funeral of Roses' was indeed Li Yijie, but the background and experience of the song were not directly related to Li Yijie. As for why Li Yijie would scold Xu Song, it involved the distribution of interests in the music industry, personal grudges, public opinion, and other factors. To be specific, Li Yijie and Xu Song were both music creators. They had some similarities in their musical styles, but they also had their own characteristics and pursuits in their creations. Therefore, in some cases, some music peers might criticize and attack the other party's works because they could not appreciate them. I'm not sure about the specific situation between Li Yijie and Xu Song, but no matter what, music is an art form. It needs constant innovation and development, and it also needs to respect and accommodate different creative styles.
