I watched again and noticed that when she was just about to talk the reason that she was punished physically, the video was cut off and turned to the next scene. It was happened twice at least.
So this is what she said:
1) She was extremely ill before.
2) Practicing FLC helped her becoming normal(?).
3) She continued practicing DaFa(?).
4) Video was edited somewhere here so the reason that she was punished was missing.
5) The video resumed with what she said how she was tortured and that she survived because of FLG. Even here is not clear.
6) She became bony-ill again after the torture.
Apparently the the most important part is cut from this video recordings. Looks like it was deliberately taken away.
