在英语日常交流中，晚上打招呼常用的说法有：

Good evening!
Hello!
Hi!
How's it going?
How are you doing?
What's up?
How's everything?

例如，你可以这样打招呼：

Person A: Good evening!
Person B: Hi! How are you doing?
Person A: I'm doing well, thanks. How about you?
Person B: I'm good, thanks. Just getting ready for bed.

当然，你也可以用其他表达方式来打招呼，比如说：

Hey there!
Good night!
How's your evening going?
What have you been up to?

不过，在不同的场合使用的打招呼方式可能会有所不同，比如在正式场合可能会使用更正式的说法，而在朋友之间或者家庭聚会中可能会使用更随意的说法。
