“朝三暮四”，汉语成语，字面意思是“three in the morning and four in the evening”，比喻常常变卦，反复无常（change one's mind frequently）。与英文习语“chop and change”意思相近，表示“to continually change one's course of action, to the confusion or irritation of others”。
- 我希望你不要总是朝三暮四的。
I hope you not chop and change your mind so often. - 在女人这方面，他也许会朝三暮四，但是谈及美食与美酒时，他却深知自己的喜好，并且一成不变。
He may chop and change when it comes to women, but when it comes to food and drink, he knows what he likes and sticks to it.
