《宋史·列传·卷一百八十七》
至于不发表自己的意见而以谦感人，和别人一起就能感化别人，如春风吹发万物，大概也没有谁知道其所以然。
至于不言而饮人以和，与人并立而使人化，如春风发物，盖亦莫知其所以然也。
As for not expressing one's own opinions but using modesty to influence others, and being able to influence others when working with them, like the spring breeze blowing on all things, perhaps no one knows the reason why.
