《太平广记·卷一百五十四·定数九》
等到李源回来，想起武十三郎的事，又找到那个村庄。看到一个小孩的体形相貌很像武十三郎，便叫： 武十三郎还认识我吗？ 
及还，省前事，复诣村户，见一童儿形貌类武者，乃呼曰： 武十三相识耶？ 
When Li Yuan returned, he remembered Wu Shisanlang, so he went to that village again. He saw a child who resembled Wu Shisanlang in both stature and appearance, so he called out: Wu Shisanlang, do you still recognize me?
