When Lin Wei returned home, she took a shower first. Seeing that the lights in Song Jin's room were off, she then picked up two rolls of papers and slipped out of the house.
Jian Zhangyun had yet to finish half a page of the work assigned to him by Jiang Su. Lin Wei sat across from him, twirling her pencil as she worked on math problems.
When Lin Wei had finished almost half of her worksheets, Jiang Su finally finished the homework Jian Zhangyun had given him.
Lin Wei handed the other worksheet she'd brought to Jiang Su: "Do the ones you can."
It was also a math worksheet, but it was for first-grade and the problems were relatively simple, all basic ones.
Jiang Su hadn't touched anything study-related for a year, so he had inevitably forgotten some things, and what's more, he was out of practice.
Solving problems also required a certain feel, thinking would set in motion faster when one was immersed in a study atmosphere everyday.
