Teach me to paste couplets! ! ! Which is attached to the left and which is attached to the right?

The first pair: the first part is "a treasure trove of geomantic omen gives birth to a hundred blessings", and the second part is "a rich family makes a fortune".

Second Mate: The first part is "Spring Festival welcomes the four seasons", and the second part is "Good luck welcomes wealth".

If you are facing the gate, stick the top part on the right and the bottom part on the left. The last word of the couplet is the upper couplet, and the horizontal couplet is the lower couplet. "Fu" is a homophonic word in ancient Chinese.

Distinguish, don't paste it wrong, because it will make people laugh.
