As Su Bing was about to be ushered back into the small room by Teacher Du, he presented his test paper, stating calmly, "No, teacher, I have finished writing. I came out once I was done. You can grade it now."
Teacher Du was both surprised and delighted. She took the test paper, exclaiming, "You finished early? Good job, good child. I'll go in and grade it, please wait a moment."
About twenty minutes later, Teacher Du emerged with the graded test paper, her stern expression barely concealing the joy playing at the corners of her mouth.
She looked at Su Bing, her admiration for the child growing. He was just a ten-year-old, yet his face had never shown a hint of panic from the beginning. His mental fortitude was not something ordinary students could match.
