"Haven't you all ever pass your mathematics exam?" Sister Wan tidied her bangs and looked at those people in surprise.
"What's the matter?" Man Man looked at Sister Wan with puzzlement.
"Little Jiang, you don't know too?" Sister Wan stared at Man Man for quite a long time before she turned her head to Jiang Changxi and asked her.
"What?" Jiang Changxi also revealed a puzzled look.
"So, you don't know that either, do you?" Sister Wan wasn't hopeful about Ling Hong at all.
"I've no idea what you are talking about." Ling Hong shrugged.
Sister Wan let out a sigh helplessly. Then, even Wu Hai looked at her curiously. And as Yuan Zhou was fairly sensitive to the word "mathematics", he also cocked his ears secretly and listened to her.
