Let's start jamming 蔡國權 - 童年 chords, familiarize yourself with these chords - Dm, Gm, Eb, F, Bb, Eb, Gm, C and F in sequence. A strategic approach would be to train at 59 BPM initially, and then accelerate to the song's tempo of 119. With Bb Major as the song's key, tweak the capo to cater to your vocal pitch and chord likes.
