• Primary Meaning: “all day long,” “the whole day,” or “day in and day out”

2. In-depth Explanation

• Context and Usage: 成天 is used to describe something that happens continuously or repeatedly throughout the day.

Cultural Notes (if applicable)

成天 is often used in everyday conversation, especially when talking about habits, routines, or repeated behavior. Because it can sound slightly judgmental, it is common in complaints from parents, teachers, or friends. For example, a parent might say their child 成天 plays games, meaning not just “all day,” but also “too much.”

A related expression is 整天, which also means “all day long.” In many situations, 成天 and 整天 are interchangeable. However, 成天 can feel a bit more colloquial and sometimes more emotional or critical.

Conclusion

成天 means “all day long” or “constantly.” It is useful for describing repeated behavior or something that takes up the whole day. Remember that it is often used in casual speech and may carry a tone of complaint depending on the situation.
