The content translated from the paper reads:
"Girl, by the time you read this letter, I will no longer exist, but my spirit will always be with you.
Your father is sorry for what he has done. The marriage alliance between your father and your mother was my idea. I originally thought that having a child would stabilize the family, but your birth led to your mother's death during childbirth.
Your father has always felt guilty, believing that he wronged your mother and couldn't get over it. He wanted to kill you, but I stopped him and had you live with a poor family to toughen you up.
You're as smart as I imagined. Even poverty couldn't dull your edge, and I am truly pleased.
I know you are content with your current life and that you wouldn't want to return to the He family. This money is a gesture from me, and I hope you will accept it.
