《论衡·卷四·书虚篇》
社会上于是流传说： 丁老头挖井在井中得到一个人。 其实，人是人生的，又不在土里出生。破土挖井，不会得到人。
俗传言曰： 丁公凿井得一人於井中。 夫人生於人，非生於土也。穿土凿井，无为得人。
It became a popular saying in society that Ding the elderly got a person from digging a well. However, a person is born from a person but not from soil. Digging the soil to get a well will not yield a person.
