After Amnesia

I know it's ridiculous But I just lost my memory I got into a car accident, and I don't know how small the chance is for me to run into it. I've lost my memory Parents are not like parents, brothers and sisters are not like brothers and sisters Friends are not like friends, even I am not like me Am I Yan Hui? Or do I just happen to look like her? Who am I? What is my lost memory?
