Cách sử dụng
"Save the day" or "save the situation" is a phrase you can use when someone does something to fix a problem or difficult situation. It means that someone has come to help or has done something to make things better, often at a time when things were looking bad or desperate. For example, a firefighter might "save the day" by putting out a fire, or a doctor might "save the situation" by finding a way to cure a disease. You can use this expression in many different situations, but it's often used when talking about something that was dangerous or difficult.
