There needs a long time to know the world's pulse.

Understanding how the world works, including its changing conditions and tendencies, takes considerable time. Quick impressions are not enough to reveal its deeper patterns.

The saying advises patience in forming broad judgments about life and society. Experience accumulated over time gives a fuller sense of what is happening and why.

Use it when someone expects to understand a complex situation too quickly, or when explaining why long observation and experience are needed before making a broad judgment.
