Is there a legendary biography of Avalokitesvara/Kwan-Yin/Chenrezig?

I've googled this, but can't find it. I know there is a tradition of writing legendary/mythological/fictional biographies (hagiographies) of monks in the Chinese tradition. Just a few days ago was the celebration of Kwan Yin's going forth day, but for the life of me, I can't find any other accounts of Kwan Yin's life as a monk or nun.
