something I found on another blog site, also called “Rock in China” (at blogspot):
A little bit about the history: The song “Don’t break my heart” is originally from Black Panther, written by ex-vocalist Dou Wei,
who at that time was still together with the famous pop singer Wang Fei (who is singing here). Though later they broke off, as Wang Fei discovered that Dou Wei had another lover. (see update)
[UPDATE] Remark by Kaisi:
Ok, so we got some more info.
