济南Day1 随记Haojin's Blog

济南Day1 随记终于,还是决定出去闯一闯。不知为何,我似乎是厌倦了学校的生活,每一次上下课的铃声似乎在震颤着我的内心。 希望能有所收获。 XIY 第一次知道飞机票打起折来居然比高铁票还便宜。 然后买了早上十一点的飞机票。 很早就起来了,老爸把我送上机场大巴,我却没想到他买了两张车票。 到了机场,通过自助值机拿到了登机牌,跟老爸打完招呼就进去安检了。机场里人也很少,很安静,就像细水流淌一样,心间

心灵鸡汤

  苏东坡是我国北宋时期的一位著名诗人。他在担任徐州知府时,以为官清廉、刚正不阿、不畏权势,执法严明著称,受到徐州百姓的称道和传颂。至今徐州城乡还流传着他不少的佳话。

  苏东坡五十岁的时候,家人要为其祝寿,苏东坡一再制止,并嘱咐家人不准宣扬。谁料,寿辰这一天,来了一个送礼人,双手抱着一盆盛开的月季花,家人便问:“请问尊姓大名,有何事”来者说:“我叫赵钱孙李,来祝寿的。”家人听罢,奇怪地笑道:“那有这样的名字呢”来者说:“我本姓赵,右邻姓钱,左邻姓孙,对门姓李,知府大人今年五十大寿,大家推荐我送一盆月月红,给知府大人做寿礼。”家人听后,知是百姓心意,本想收下,但大人从不收礼,只好叫来者说出理由,那人思忖片刻,道出:“花开花落无间断,春去春来不相关。但愿大人常康健,勤为百姓除赃官。”家人把诗写在纸上,叫仆人把诗送给苏东坡看,让他来处理此事。不一会苏东坡出来,亲自收下那盆月季花,笑着咏诗道:“赵钱孙李张王陈,好花一盆黎民情。一日三餐抚心问,丹心要学月月红。”

  后苏东坡虽赋闲回家,但他一生清正廉明、惩贪除恶的好名声却在民间永远流传。
