《太平广记·卷四百九十九·杂录七》
铜乳的臭味，并肩站着，前后走着都能闻到，你和他们在一起，不觉得可耻，怎么竟然讥讽我和山野中有学问的人交往呢？
铜乳之臭，并肩而立，接迹而趋。公处其间，曾不嫌耻，乃讥予与山野有道之士游乎？
The smell of copper breasts, standing side by side, and walking back and forth can be smelled. You don't think it's shameful to be with them. How can you actually mock me and those who have knowledge in the mountains and fields?
