"I can even make airplanes and cannons!" Pei Qin started to bamboozle Little Radish with a serious face.
Chang Yonglin blinked, "What's an airplane and a cannon?"
"An airplane is like a kite, but it can carry people and fly in the sky!" Pei Qin explained to him.
"I don't believe it!" Chang Yonglin was very sure of himself, "I have never seen anything without wings fly in the sky, no, even those with wings sometimes can't fly. Chickens, ducks, and geese all have wings, and they can't fly!"
Pei Qin laughed heartily.
Chang Yonglin pouted slightly and asked her again, "Didn't you say you're really good at calculations? Grandpa wants me to learn the abacus, but I just can't get the hang of it. Could you teach me?"
"Er..." Pei Qin touched her chin, "Actually, I'm not that good with the abacus!" She was telling the truth.
