"That's because you kids were too naughty, can't blame your father for kicking you."
Cai Xiufen gave a light "hmph" and said, "Your little aunt was well-behaved since childhood. Both your grandfather and I spoiled her as much as we could, never had to teach her a lesson. Now, your little aunt knows how to teach kids; that's her own smartness, nothing much to do with me or you."
Kang Yiyang sighed, "My little aunt is just a bit older than me, yet how is she so insightful?!"
"Can't figure that out?!"
Cai Xiufen glanced disdainfully at her eldest grandson, then proudly said, "Your little aunt has been smart since she was a kid."
"I get it now, Grandma, you're saying I'm silly, not as insightful as my little aunt."
Kang Yiyang pretended to be aggrieved, but unexpectedly, Cai Xiufen didn't even look at him and blurted out, "If you know it, why say it out loud? It seems your brain really isn't working well."
