There is a modern poem that probably says that the old man regretted not listening to his father before he died and wasted his youth? Modern poetry.

Youth is gone forever,

Work hard while you are young,

Nothing, nothing, sadness,

There are two lines of tears in old time and space.

My father's warning is still in my ears,

Look at today, the fallen leaves still have to find their roots.

Regret surrounds the mind,

Be ashamed of my father's teaching.

The road to the grave is not peaceful,

What face will be kind and respectful.
