《太平广记·卷四百一十二·草木七》
到夜里，母亲做了一个梦，一人对她说： 我的坟在这三百年了，你的两个孩子常常要毁掉它，全靠你保护了它，又给我好茶喝，虽然身体烂在地下，但是哪能忘桑荫之德呢？ 
及夜，母梦一人曰： 吾止此冢三百余年，母二子恒欲见毁，赖相保护，又飨吾嘉茗，虽泉壤朽骨，岂忘翳桑之报？ 
At night, the mother had a dream in which someone said to her: My tomb has been here for three hundred years. Your two children often want to destroy it. Thanks to your protection and the good tea you gave me, although my body is rotten in the ground, how can I forget the kindness of Sang Yin?
