Yun City, by the street, an elderly lady with white hair was pushing a small cart, her steps unsteady. This was a small snack stall selling specialty secret egg pancakes, with a fragrance that filled the air.
"Granny, I'd like to buy one of your egg pancakes!"
A charming young lady, carrying a backpack and wearing a high school uniform, approached with a smile.
"Alright," the old lady replied kindly, stopping to open the lid, and placed an egg pancake in a paper bag, handing it to the charming young lady. "Little girl, it's 6 yuan."
The charming young lady fished out a handful of crumpled bills from her pocket—some five-yuan notes, some ten, and even hundred-yuan red notes.
She picked out a ten-yuan note, about to pull it out, but after glancing at the old lady, she smiled sweetly and chose the red bill instead, handing it to the old lady: "Here you go, Granny!"
