Dong Menwu, a person of the state of Wei, were not very sad when his son died. His servant girl was surprised and asked, "Master, you doted on your son so much before your son died. Now your son is dead, but you are not very sad about it. I wonder why." Dong Menwu said to her, "I used to have no son, and I wasn't sad then. Now my son is dead, it is just like before to me. So why should I be sad？" 魏國人東門吳死了兒子后，并沒有變現(xiàn)出過分的憂傷。 婢女感到奇怪，就問主人：“您平時對兒子的疼愛稱得上是舉世無雙，現(xiàn)在他死了，卻沒有看見您有多少憂傷的表情，這究竟是什么原因呢？” 東門吳告訴她：“我以前沒有兒子，那時候并不憂傷，現(xiàn)在兒子死了，等于沒有兒子，這和以前一樣，我為什么要憂傷呢？”
