He Fusheng tied the ox to a tree by the door and walked into the store with his hands behind his back.
Ning Chenguang followed closely behind him, not leaving a step.
"How much is this cake per pound?" He Fusheng pointed at the one he could swallow in one bite and asked.
"Three dollars and seventy cents a pound!" the shop assistant said.
"Give me three pounds!" After saying that, He Fusheng turned his head and asked Ning Chenguang, "Guangguang, your brain works great, can you calculate for me, how much do I give them in total?"
"Eleven dollars and ten cents!" Ning Chenguang answered promptly.
"This child is really smart, not a penny off." The shop assistant flicked the abacus beads with a smile and praised Ning Chenguang.
"Indeed! This kid's brain is even better than a calculator," He Fusheng said happily.
The cake was bought, and they got back on the ox cart and continued their way home.
It was after two in the afternoon when He Fusheng finally brought Ning Chenguang home.
