Help me think of a couplet.

Geckos swim in iron prisons, regretting thousands of crimes and repeating them.

Jinsuo is very happy and his body is eager to clean up.

Horizontal batch: point iron into gold

Note: Read by split method:

The prison faces the wall, and the gecko swims (the gecko swims over the wall to steal). He will always regret his thousand sins, and he will repeat them once and for all.

The golden lock is happy (opening the shackles of the soul), and the body and mind are bathed (purifying the soul). If you want to clear the waves (eliminating all kinds of bad things), the prodigal son will turn back and return to the shore. Among them, "forever" and "longing" are homophones of "swimming" and "bathing".
