Juhua suddenly stopped writing. She mentally calculated the total expenses and jotted down the number. Then, as if remembering something, she rested her brush on the edge of the inkstone. Getting up, she grabbed a comb and began to untangle Huai Zi's long hair while talking to him.
"Huai Zi, I just remembered what I wanted to tell you earlier before you interrupted and made me forget. When you have the time, could you go to the market and check if my abacus is ready?"
Huai Zi replied, "I'll go in a couple of days. I need to take the wood ear mushrooms to the market to sell anyway, so I'll bring it back then. Juhua, do you really know how to use an abacus? You learned it just from reading a book?"
Juhua deliberately put on a smug expression. "It just proves how smart I am! Mathematics and Planning explains everything very clearly. Just stop asking; I'll show you how to use it once it's here."
