大惊小怪
Much matter of a wooden platter.
Like a hen with one chicken.
A storm in a teacup.
Go off the deep end.
Much ado about nothing.
Look like a dying duck in a thunderstorm.
Make a song and dance about something.

eg：Such things happened very often, don't be much matter of a wooden platter.

反义词：若无其事 As if nothing has happened.
