"Grandma, try this burger, it's really delicious."
"Mmm, it smells so good, Xue'er, you eat, too."
In the simple room, a very ordinary, yet warm scene is unfolding.
The frail grandmother, with a face full of wrinkles, now shows a smile that has been absent for a long time.
Her granddaughter is fortunate.
She won three years' worth of free meal tickets.
Her precious granddaughter is in the growing phase, and she, being a grandmother, is incapable; even if she collects trash day and night, it's hard to give her granddaughter a better life.
The elderly woman had thought about selling blood.
Unfortunately, she was too old, and no institution was willing to take it.
"Grandma, eat a bit more." Lin Xue'er gave most of the meat to her grandma.
"You eat more, too, grandma's appetite is small, I can't eat that much."
...
Unbeknownst to the two people in the room, all these scenes and sounds were being captured by a tiny drone parked by the window.
