recognize the whole through observation of the part

In Chinese, CH ǔ Q ì é ry ǔ is pronounced in pinyin. It means that the cornerstone of the pillar is wet, which is the sign of rain. It means that you can know its development direction when you see a sign. It comes from the theory of distinguishing traitors.

The source of the idiom is Su Xun's on distinguishing traitors: "the moon faints and the wind blows, the foundation moistens and the rain falls."
