Definition
To transform heaven and earth; to bring about a monumental change in the world or nature.
How it's used
This idiom carries a grand, ambitious tone often used in political or historical contexts to describe radical, sweeping changes. It implies a complete overhaul of the existing order or environment, making it sound much more dramatic than simple words like 改變 or 改革. You will frequently hear it in speeches or formal writing, though it can be used ironically in casual conversation to mock someone's overly optimistic or unrealistic plans.

Common mistake
Learners often mistake this for a simple synonym of 'to change' or 'to improve'. Because it implies a total, earth-shattering transformation, using it for minor personal changes or small household adjustments sounds comically exaggerated and unnatural.
