"Of course! Who do you think your sister-in-law is? She's the smartest amongst all of you! Ever since she started learning to read with Xiaoquan, she took the initiative to read maths textbooks. It didn't take long before she got the hang of it, I promise you. Next time there's a chance, wouldn't you like your sister-in-law to teach you maths?" Liuliu raved without a trace of pretentiousness, proud of her intelligence.
"Really? I want to learn. Sister-in-law, my aunt asked me to help teach your brothers today. I agreed, but at the moment, that's impossible. We don't have writing tools like brushes, ink, paper, and ink stones. How about this - in a few days, I'll go to town and buy these things for them?" Xiaojie proposed, ready to pay out of her own pocket.
