ASTROLOGY PLANETS PROFESSIONAL NEEDED

Hii

Id like to know what mercury, venus, mars and jupiter signs are all about in astrology.

I know a bit of their 'functions' but are they suppose to match with someone else's astrology planet?

Not sure how to ask my question but here;

is someones mercury suppose to match someone elses mercury?

or mercury should match someone elses moon sign for exemple?

Anything can match anything, it's the general combinations that make the relationship. And also planets in the other person's houses. It paints a picture, some aspects are better for certain people, but not others. It's all very specific to each person. You see patterns and you work it out.
