She approached Ning Zhao, stole her work, took it to compete in world-level competitions, and successfully won the championship.
She successfully became the piano prodigy girl everyone talked about.
Since Ning Zhao never made contact with the outside world, the Tang Family was unaware of this matter. And Ning Zhao herself was even less likely to expose her.

So, in a fit of madness, she used a scheme to cripple Ning Zhao's hands, ensuring she would never play the piano again in her life.
Ning Zhao went mad.
The only solace left in her world was the piano, yet even that last comfort was being strangled by someone.
Finally, when the servants of the Tang Family weren't paying attention, Ning Zhao shattered the mirror in her bedroom, ending her own life.
