27.Why does this poem often appear in my mind?
Yesterday, the poet Cai Tianxin, someone knows that he is also a famous math science writer in China. Cai asked me to make an appointment, recommend a poem, and write a recommendation reason. 100 words will be fine.
I thought about it, and recommended the first "under the North Gu mountain" of wangwan in Tang Dynasty, in which the famous sentence is: "the tide is flat and the two sides are wide, and the wind is hanging. The sea is living day by day and the night is still alive, and the spring of the river enters the old year. "
Especially the sentence "the sea is living day by day and the night is still alive, and the river spring enters the old year".
Sea, day, night, river, spring and year are all very broad concepts, the ultimate people can think of in time and space, and the fireworks in the world are all refined.
There is no one in this poem, but you know clearly that there is a man with a great state behind it.
Why does this poem often hit my head? Maybe because of the human disturbance, a poem is needed to pull itself into a very large coordinate system and then to look back to the reality.
Read a few words silently, even if it is mentally to a spacious place to stretch a big lazy.
为什么这句诗经常浮现在我脑中？
昨天，诗人蔡天新老师，有人知道他也因为他是国内著名的数学科普作家。蔡老师找我约了个稿，推荐一首诗，而且写个推荐理由，一百字就行。
我想了想，就推荐了唐代王湾的那首《次北固山下》，其中的名句是：“潮平两岸阔，风正一帆悬。海日生残夜，江春入旧年。”
尤其是其中那句“海日生残夜，江春入旧年”。
海、日、夜、江、春、年，这都是极阔大的概念，是时间和空间上人能想到的极致，把人间的烟火气都给炼没了。
这句诗里面确实没有人，但是你又分明地知道，背后有一个境界极大的人。
为什么这句诗经常撞到我的脑子里？也许是因为人间纷扰，需要一句诗把自己拔到一个非常大的坐标系里，再来反观现实。
默念几句，就算是精神上到一个宽敞地方伸个大懒腰吧。
