Teachers who have studied couplets, please give us your advice!

One way to judge the ups and downs of Spring Festival couplets is to see whether the last word of each couplet is flat or silent. Remember a rule, "flat set", which means that the last word of the next couplet should be flat. But we can see that the last word of these two couplets is Pingyin.

"Lai" is the second sound and "Kai" is 1 sound, so the word "Kai" is flatter than the word "Lai". Then it should be judged that "high-tech jobs in Honglian bring happiness" is the first part, and "happy guns are everywhere" is the second part.

Another thing to note is that couplets should be posted from right to left, with the upper couplet on the right and the lower couplet on the left.
