"Bay" can also be used in more complex sentences or idiomatic expressions. For example: - "Vệ tinh nhân tạo bay qua bầu trời." (The artificial satellite flew past in the sky.) - "Đạn bay rào rào." (Bullets flew past.)
"Bay" is a versatile verb in Vietnamese that primarily means "to fly," but it can also imply fading or disappearing in certain contexts.
