The Vietnamese phrase "ba bó một giạ" literally translates to "three bundles make one basket." However, in everyday usage, it means "a sure thing" or something that is guaranteed to happen. This expression suggests that if you have three bundles (or certain elements), they will surely come together to form a complete unit (the basket).
Understanding "ba bó một giạ" helps you grasp the idea of certainty in Vietnamese culture, emphasizing the importance of having all necessary elements for success.
