Mr. Guo is a single dad who loves his daughters and calls them his two angels. But it’s been hard to raise them alone. He’s poor and his youngest daughter was born with health problems and ended up in a coma. He remembers with deep sadness, “My wife told me she was too tired to take care of a sick child, and she divorced me. I looked into the crying faces of my girls and told them, ‘You lost your mother, but you still have your father. And I'll take care of you.’” He secretly wondered how he’d do it, especially when he found out that XinYa had holes in her heart, and she started having heart attacks.
