It's a semi-imaginary story. I made up a family like this from the Tang Dynasty, and then plucked such a little girl from it. She had poor health since she was a child and grew up sickly. She was in mourning before she even had haircuts. When she closed her eyes and opened them, she found that she had become smaller. Could it be that she was reborn? The little girl grew up religiously and curiously living in the 21st century.
