Cách sử dụng
The expression "a drop in the ocean" means a very small amount compared to what is needed or expected. It can be used in situations where there is a big problem or task, and someone does something small to help. For example, if a country needs billions of dollars to fight poverty and someone donates only a few hundred, it can be said that the donation is "a drop in the ocean" compared to what is needed. It can also be used to show perspective and to convey that something is not significant or impactful in the grand scheme of things.
