1. You surprise me.

2. You surprised me.

Hi, my question is, which of the two sentences is correct? Or if they are both right, what is the difference? Thank you!

They are both right.
The first is present and describes something that happens regularly, habitually; the second is past and describes a single event.

Thank you, CJ!

It's easier for me to understand "You surprised me."

Can I see "You surprise me" as "you often give me surprises", or "I get one surprise after another from you as I come to konw you"? But in this sence, will "You really surprise me" or "You always surprise me" sound more natural?
DearYolandaCan I see "You surprise me" as "you often give me surprises"
Yes. That's one way of seeing the meaning.
DearYolandaor "I get one surprise after another from you as I come to konw you"?
This is also possible, but less likely I think.
DearYolandawill "You really surprise me" or "You always surprise me" sound more natural?
They both sound natural.
