Let's start jamming 草蜢 - 深淵 chords, Practice these chords sequence - Fm, Eb, Gm, Cm, Dm, Gm, F, Am, Bb, Eb, Bb and Cm. I suggest starting at a calm pace of 35 BPM, and as you gain confidence, approach the song's BPM of 70. Align the capo with your vocal depth and chord choice, bearing in mind the song's original key: Eb Major.
