《太平广记·卷二百零七·书二》
写完了，王羲之告辞归去。这个学生送他回到郡里，待到返回自己家中时，发现他父亲已经将老师的题字都刨去了，一个字也没留下。
门生送王归郡，比还家，其父已刮削都尽，儿还去看，惊懊累日。
After he finished writing, Wang Xizhi took his leave and went back. This student sent him back to the county. When he returned home, he found that his father had scraped off all the teacher's inscriptions and not a single word remained.
