There is a brick on the left and right of the neighbor's door. What do you mean?

Neighbors put bricks on the left door to show that everything goes well in the new year.

Putting bricks means "throwing bricks to attract jade". The so-called throwing bricks to attract jade refers to a trick of confusing each other with similar things, making them ignorant and deceived, and then achieving their goals.

"Brick" and "jade" are metaphors. As we all know, fishing needs bait, and the fish will only take the bait if they taste a little sweetness.

The "bricks" here are bait; "Jade" is the purpose of behavior, that is, the result of the other party speaking and doing things according to their own wishes.
