管子，一位生活在春秋时期的齐国人士，他是法家的始祖。
在《管子·形势解》这本书里，他描述了风和雨的特点。
风是空气随风向而动，并不会因为你是富贵还是贫贱，长得美或丑，就躲开你。
风对待每个人都是公平的，它不会偏爱任何人。
雨是会沾湿物体的，它所落下之处并不会有大小强弱的分别。
无论是小草还是大树，雨都会落在它们身上。
雨也是至公无私的。
尽管人们有时会遇到风雨吹袭，但大家并不会埋怨风和雨。
因为风和雨没有固定的方向或特定的喜好，它们只是按照自然规律行事。
因此，“大公无私”这个成语就被用来形容那些公正无私、没有任何偏见的人。
他们处理事情时，会一视同仁，不偏袒任何一方。
这就是“大公无私”的含义。
Guanzi, a man who lived in the State of Qi during the Spring and Autumn period, was the ancestor of the Legalist school of thought.
In his book "Guanzi: Explanation of Situations", he described the characteristics of wind and rain.
Wind is air moving with the wind direction, it will not avoid you because you are rich or poor, beautiful or ugly.
Wind treats everyone fairly, it does not favor anyone.
Rain is something that wet objects. It falls without distinction of size or strength.
Whether it is a small grass or a big tree, rain will fall on them.
Rain is also great and fair.
Although people sometimes encounter wind and rain, they do not blame the wind and rain.
Because wind and rain have no fixed direction or specific preferences, they just act according to natural laws.
Therefore, the idiom 'Great and Fair' is used to describe those who are fair and impartial, without any bias.
When dealing with things, they treat everyone equally, without favoring any one side.
This is the meaning of 'Great and Fair'.
