About writing couplets

What you said is not relative. According to what you said, "dragon day" is relative to "empty", which can't be done. Besides, according to your name, it should be "dragon day" and "Kongming". I made a couplet for you. I don't know if you are satisfied. As follows:

Hidden dragon is ambitious in the depths.

Realize that what you mean is not empty talk.

Horizontal criticism: striving for strength
