The Vietnamese phrase "lập kỷ lục" means "to achieve a record" or "to set a record." It is commonly used in contexts where someone accomplishes something remarkable that is noted as the best or highest achievement in a particular area.
While "lập kỷ lục" specifically refers to achieving a record, "kỷ lục" alone can refer to the record itself, which can have different implications depending on context (e.g., a world record, national record, etc.).
"Lập kỷ lục" is a versatile phrase that conveys the idea of achieving something exceptional.
