Please translate this poem into English.

I know

Joy is the inn of life.

A painful journey of life

When my heart is heavy

The best gift

It's a quiet sky.

I know

You will always be confused.

You will always know

When the night comes

You will feel

Some people are concerned about

I know

When you dry your tears

Smile

Then I'll tell you gently

Look how beautiful it is

Sophora japonica is fragrant and moonlight is beautiful.
