I tried to find the translation of CLH'84 opening and closing themes but failed, so I asked my Chinese Malaysian friend to translate it for me. Sompong from the YT video below provided me with the script of the opening theme and Min Chi translated it for me; hence my gratitude for both of them. I obtained the closing theme script from Musixmatch and Min Chi translated it again for me (thanks again!). I love both songs. I really dig the opening theme for it truly captured who Chor tai-gor was, while the closing theme reminds me of CLH/SSC relationship.
