At the Lin Lei household.
A boy named Lin Xiaonian, squatting on the side like a porcelain doll, blinked curiously.
The girl cried with tears streaming down her face, clutching a booklet while wailing aloud.
"If you can't read, learn slowly, what are you crying for if you can't understand?" Mrs. He rubbed her forehead, clearly exasperated, "People were just passing by the door, and you, with your windmill, insisted on exchanging it for their book."
"It wasn't an exchange." The little girl sniffled, solemnly saying, "It was a purchase, I bought it with the windmill."
"Straighten your tongue when you speak." Mrs. He couldn't help but laugh in exasperation, "What's the difference?"
"The piglet said, exchanging doesn't cost money, buying things costs money." The little girl earnestly explained.
"So what?" Mrs. He asked.
"If it costs money, then it is… it is…" The girl was momentarily puzzled, then as if struck by sudden realization, she said, "then it is valuable."
