Hua Manman carefully unfolded the wad of paper.
The paper was palm-sized. On it was a drawing of a grid, and the square in the top-right corner was circled in red.
Hua Manman and Qing Huan both stared at it, completely bewildered.
'What is this?'
Hua Manman turned the note over and over, looking for any other clues.
But there were none. The only thing on the paper was this strange grid.
Hua Manman studied the grid all morning but couldn't figure anything out. Instead, she just ended up with sore, strained eyes.
Qing Huan reminded her, "It's time for lunch."
Hua Manman rubbed her eyes and got up to eat.
As she passed a curio shelf, Hua Manman suddenly stopped.
She turned her head to look at the curio shelf beside her and abruptly asked a question.
"Don't you think this shelf looks a lot like the grid drawn on the paper?"
Qing Huan didn't know what a "grid" was.
