"Could I learn to write and fight with you concurrently?" Eagle pleads.
"Why not? As long as you want to learn, your elder sister is here to teach you. Xiaoguo, do you also want to learn to fight? Your sister-in-law will teach you too!" Liuliu reluctantly responds to her younger brother, noticing Xiaoguo staring at her with wide eyes. Fine, she decides, I'll teach you too.
"I don't want to learn. I prefer learning Bead Calculation. I want to become a shopkeeper, so why would I need to learn to fight?" Xiaoguo is not interested in being thrown around by his sister-in-law. He won't learn that.
