Zhao Shi only wished she could die when her sister-in-law insisted there was nothing wrong with her arithmetic, though mastering bookkeeping might not be so certain—moving her lips, she dared not retort, "Mother, I will try my best to teach my sister-in-law."
She hadn't finished speaking, thinking that if she truly couldn't teach her, then it would be her sister-in-law's own problem.
Lady Li felt that Zhao Shi was scheming, always seizing the chance to put her down, "Mother, I will make sure to keep track of every entry in the accounts."
She absolutely wouldn't let her younger siblings outdo her!
Zhulan watched Lady Li quietly, suddenly realizing there were advantages to her sister-in-law's paranoia. Imagining Zhao Shi was against her every day, Lady Li would be especially motivated to improve. The way Zhulan saw it, no wonder those in power liked to play the balance game—lifting someone's spirits could often be more motivating than suppressing them!
