Cách sử dụng
The expression "turn back" is used when one is returning to a previous place or direction. For example, if you are on a road trip and realize you forgot something important at home, you might have to turn back and drive back in the opposite direction to retrieve it. It can also be used figuratively to mean reconsidering a decision or changing one's mind. For instance, if you were planning to go out with friends but suddenly feel too tired, you might decide to turn back and stay home instead.
