How to use 都……了
都 + Time + 了
都 with final 了 can emphasize that a situation has already reached a relevant point. A time, age, or event may follow 都, and the speaker treats that fact as significant. This use does not quantify a plural group even though “all” is another familiar meaning of 都.
The sentence often supports a reminder, a complaint, or an argument that another action should now change. A following clause with 还 can highlight a situation continuing despite the milestone already reached. 已经 can also appear for added clarity or emphasis, but it is not essential. Read the speaker's expectation from the context rather than assuming that every use communicates annoyance or surprise to the same degree.
