The Vietnamese word "đánh đu" means "to swing." It refers to a traditional activity where people swing back and forth on a swing, often made of bamboo, which is a common sight during festivals in certain regions of Vietnam.
While "đánh đu" primarily means "to swing," it can also imply a sense of playfulness and connection, particularly in romantic contexts. Additionally, it might be used in a broader sense to describe engaging in lighthearted activities.
