Grandma looked at her: "If something goes wrong, Sidong's lifelong effort will be in vain, and he might even get slandered; if nothing goes wrong, it's just a wasted trip to the school, so what's the harm?"
Mom found this reasoning very convincing.
She stood up and took the car keys: "Let's go, bring it back."

In the office, they got the sample paper, and Professor Sheng opened it, finding that the sample paper appeared different from the one he had previously placed, and its position had also changed.
"Tangtang was right, someone tampered with my sample paper." Sheng Sidong's face changed dramatically.
