Song Jixue's eyes shone like the stars at dawn as she asked Yuan Yunzhong, "Then, can my eldest sister do calculations too?"
Yuan Yunzhong gently coughed once, avoiding the topic, and returned to the main point, "You see, learning mathematics is also very important, isn't it?"
Song Jixue was immediately led astray by Yuan Yunzhong and nodded her head.
Yuan Yunzhong continued, "But we don't necessarily learn things because they are useful, right?"
Song Jixue did not understand.
Yuan Yunzhong straightened the beaded flowers at the tips of her hair and said warmly, "Besides mathematics, what else do you like?"
Song Jixue thought for a moment and replied, "I like my mother, my sisters, and my father. Does that count?"
"It counts!" Yuan Yunzhong laughed, "Anything else?"
Song Jixue thought harder, then shook her head, "No, that's it."
