I've been looking for this song for years! I've heard it once in a public transport, and because I didn't know chinese the most I can do was humming it's melody on Shazam but It's fucking useless. I have been all over youtube looking for this but never found it, it's truly a miracle how a song being heard only once was able to stay in my head for god knows how long. Finally, just now some guy in a video of Chinese eggman meme mentioned a link to a good song but suprisingly it's this song and I was dumbfounded. Thank you, random guy, you're my hero and my journey to find this song is finally over. Thank you, you saved my life.
