《太平广记·卷二百零七·书二》
王献之五六岁时学习书法，一次父亲悄悄走到他身后用手拔他的笔，拔不下来，赞叹他说：这个孩子在书法方面，将来一定会成大名的。于是，亲手书写《乐毅论》给王献之，让他效仿临摹。
子敬年五六岁时学书，右军从后潜掣其笔，不脱。乃叹曰：此儿当有大名，遂书《乐毅论》与之。
When Wang Xianzhi was five or six years old, he was learning calligraphy, once his father came behind him and pulled his pen, but couldn't pull it out, so he praised him: this child will become a great calligrapher. Then, he hand-wrote "Le Yi Lun" for Wang Xianzhi to help him practice.
