Cách sử dụng
The expression "deep down" means something that is really true or is at the core of someone or something, even if it might not be obvious on the surface. It's often used to talk about feelings or desires that someone may have, but they don't necessarily share with others. For example, "Deep down, I know I want to study art, but I'm afraid to pursue it." Or, "Deep down, he really cares about her, even though he doesn't show it." You could also use it to describe something that is hidden or buried, like "Deep down in the ocean, there are creatures we haven't even discovered yet."
