Creepy dissonant piano jingle from Chinese mobile ads, paired with uncanny AI avatar gestures [fully lost]

China’s most viral lost media of 2026.https://m.bilibili.com/video/BV1Rbgw64EL9

According to people with piano training, this piece is highly unconventional. While it follows a fairly standard ii‑V‑I chord progression, each chord is crammed full of extra modal notes. It sounds like something made by smashing down piles of random notes as a kid would.

It surfaced widely in Chinese advertisements around 2019. It has recently been rediscovered and has gone viral across Chinese‑language internet communities

Even though multiple Chinese communities are already searching for this track, I would still like to ask: has anyone outside of China ever heard this piece? Some people theorize it originates from an old YouTube video，say It is experimental music uploaded by Noriaki 8039
