Excuse me, is the singer "Xiaoyue" and singer "Gong Yue" of the album "Riding to Lhasa" the same person! Gong Yue's nickname seems to be "Abortion".

It's the same person. If you are a veteran fan, you can hear it from the timbre and style. Abortion is just that Gong Yue's records are made by different companies and use different stage names, because different companies generally use independent stage names to promote and publicize their sales.
