Ping An is a little girl who has a special little hobby - picking up special small stones.
One day after school, Ping An picked up a pebble that fell from the sky. He looked at the pebble and fell into deep thought, but because of this, he escaped from a speeding car that did not obey traffic regulations. Ping An looked at the speeding car and fell into deep thought again. Ping An: Wow, I almost got hit!
Ping An is a cool girl~
Purpose: obey traffic laws
