有位客人到某人家里做客,看见主人家的灶上烟囱是直的,旁边又有很多木材。
客人告诉主人说,烟囱要改曲,木材须移去,否则将来可能会有火灾,主人听了没有
作任何表示。
不久主人家里果然失火,四周的邻居赶紧跑来救火,最后火被扑灭了,于是主人
烹羊宰牛,宴请四邻,以酬谢他们救火的功劳,但并没有请当初建议他将木材移走,
烟囱改曲的人。
有人对主人说:“如果当初听了那位先生的话,今天也不用准备筵席,而且没有
火灾的损失,现在论功行赏,原先给你建议的人没有被感恩,而救火的人却是座上客,
真是很奇怪的事呢!主人顿时省悟,赶紧去邀请当初给予建议的那个客人来吃酒。
【学习啦】心得:预防重于治疗,能防患于未然之前,更胜于治乱于已成之后。SIEMENS西门子 6FC5210-0DF22-0AA0 6FC5210-0DF22-0AA0 6FC5210-0DF22-1AA0
