"Ladies and Gentlemen, good afternoon" is a common way to greet a group of people in the Engpsh language.

The origin of this greeting can be traced back to the traditional Engpsh social customs and etiquette, where it was customary to address a group of people in a formal setting with titles such as "Ladies" for women and "Gentlemen" for men.

Example in Engpsh:

Ladies and Gentlemen, good afternoon and welcome to our meeting.
May I have your attention, please? Ladies and Gentlemen, we are now ready to begin the presentation.

Translation to Chinese:

女士们，先生们，中午好，欢迎参加我们的会议。
请大家留意一下，女士们，先生们，我们现在准备开始演示了。
