Jia Feijiaer - Yun'er, Li Yijun - Yudie, folk songs are like spring river water (3 better versions, Huang Ying, Yao Beina, Siqingerile, depending on which style suits you), Bai Ice - Hope, F.I.R - Raining Cherry Blossoms - Crescent Bay, Christine Welch - Searching and searching, Xu Huaiyu - Fenfei, Zhuo Yiting - Prayer, Xinran - Millennium Destiny. The melody of the song I chose is absolutely fine. It depends on which song you can sing. Kugou and Xiami Music can find these songs. Let me know the result after the competition is over.
