Cách sử dụng
When we say "a link in the chain," we are talking about a part of a process or system that is connected to the next part like links in a chain. Each link depends on the previous link, and if one breaks or is missing, the chain won't work properly. So, when we use this expression, we mean that every part of the process or system is important, and we need all the parts to work together to make it successful. It can be used in different contexts, like in a production process or a team project, to emphasize the importance of cooperation and collaboration.
