It took several years to realize that you were wrong. Please describe it in a poem.

One misstep makes an everlasting regret, and then look back for a hundred years.

The past is empty, still like a dream.

A moment that should last forever has come and gone before I know it.

Dong Feng Xie, who is in a bad mood, has been very depressed in recent years. No, no, no.

Chang 'e, I must regret eating the elixir, and now I am alone, in the blue sky, singing every night.

Looking back on sadness, I will remember the past, and the wind will blow thorns into salary.

Looking back at the west wind, sadness comes from it, and the rain is scattered in the empty temple.
