《太平广记·卷二百二十·医三》
医生说：五脏六腑里没有别的什么，如果胸中有东西，用嘴攻击你的乳，乳就痛，但痈不能动呵。
医者曰：脏腑无他，若臆中有物，以喙攻其乳，乳痛而痈不可为也。
The doctor said: There is nothing else in the five internal organs and six viscera. If there is something in your chest, it will attack your nipples when you open your mouth. Your nipples will be painful, but the boils cannot move.
