Luo Qingxue is an academic achiever, and his favorite thing to do is study these math competition problems. This particular problem is meant for the students in the class who are participating in the math competition. After copying it onto the blackboard, he pondered for quite a while but still couldn't come up with a correct solution. He really didn't know how to proceed, having tried several methods without solving this difficult problem. Even just now, he had been thinking about how to solve it, and planned to ask other teachers after the teacher-parent meeting if they had any ideas.
At this moment, seeing those few lines and companies on the blackboard, suddenly he felt a sense of epiphany—how could he not have thought of this? Who came up with this? At that moment, he was really filled with disbelief. She really wanted to ask, "Who solved this? To have such a good approach." But with so many parents here, she felt embarrassed.
