Used, what the 2nd floor said is wrong, I am level 9. I think only those who have passed the exam have the right to speak. Flight of the Bumblebee shouldn't be used. I didn't choose "Concert Etude" at the beginning. If you use the book compiled by Liu Jintang, I still recommend that you play "Dadingzi Mountain High". "High" is a folk song, but it is very charming and very simple. If you don't like the melody and quality of folk songs, then I suggest you play "Er Quan Ying Yue", "The Moment of Music" and "Humorous Song". These are all The repertoire I practiced at level 6 is for your reference (I prefer "Er Quan Ying Yue")
