To learn 隔壁老樊 - 你的姑娘 chords, anchor your practice on these foundational sequence of chords - Db, Ab, Bbm, Fm, Gb, Db, Ab, Db and Ebm. I suggest starting at a calm pace of 60 BPM, and as you gain confidence, approach the song's BPM of 120. Configure the capo to your vocal range and chord preference, remembering the key of Db Major.
