On New Year's Eve, a three-and-a-half-year-old little milk baby picked up a father in a pile of garbage. She dragged the bruised and battered man home, and used childish words to pull him back from the desperate situation. Soon after, she successively picked up two teenagers abandoned by the whole world—one gloomy and unsociable, the other dim and devoid of light. No one expected that this little tot with a small schoolbag and a pink little shovel would warm this pieced-together home until it was boiling hot. And those who secretly wanted to trip them up soon found out that whoever you mess with, you must not mess with the milky little one in her family.
