Cách sử dụng
When someone or something collapses or falls in a heap, it means they fall down and become scattered and disorganized, usually in a messy heap. This expression is often used to describe people or objects that collapse due to exhaustion, weakness, or sudden impact. For example, someone can collapse in a heap after running a long distance or a stack of books can fall in a heap if knocked over. It is a figurative expression, meaning it is not to be taken literally.
