Teach me to paste couplets! ! ! Which one is attached to the left and which one 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 four seasons of happiness", and the second part is "Good luck welcomes wealth from all directions".

if you are facing the gate, stick the upper couplet to the right and the lower couplet to the left. The last word of the couplet is the upper couplet, and the flat couplet is the lower couplet. "Fu" is a homophonic word in ancient Chinese.

make a clear distinction, but don't post it wrongly, because it will make people laugh.
