A kindergarten teacher in Hebei province decided to record the happy faces of the children in her class.
She lay on the floor and held a phone as she took a video of the children while a colleague dragged her by the feet across the classroom.
The children are seen in the video waving their hands at the teacher, and smiling happily as she slides past them.
"I thought of filming from a different angle," the teacher says. "I wore a thick coat for it, but I hadn't expected the kids to become happier as I took the video."
"This teacher really loves kids," said one person. Another joked: "It's not bad that she sweeps the floor at the same time!"
