《史记·七十列传·吕不韦列传》
吕不韦唯恐事情败露，灾祸降临在自己头上，就暗地寻求了一个阴茎粗大的人嫪毐作为门客，时常放纵淫乐，要嫪毐用他的阴茎贯穿着桐木所做的小车轮行走，并设法让太后知道此事，以此事引诱她。
吕不韦恐觉祸及己，乃私求大阴人嫪毐以为舍人，时纵倡乐，使毐以其阴关桐轮而行，令太后闻之，以啗太后。
Lu Buwei was afraid that things would be exposed and that disaster would befall him, so he secretly sought a man with a large penis, Lao Ai, as a guest, often indulging in fornication, asking Lao Ai to put his penis through a small cartwheel made of paulownia wood to walk, and trying to let The queen mother knew about this, and used this to seduce her.
