What song did Wang Hongen sing at the black wedding?

Is Dora's favorite poem, Psalm 23:

God is my shepherd and I will never want it.

He makes me lie down in the green grass and leads me to the quiet waters.

He revived my soul and guided me on the path of justice for his name's sake.

Although I walk through the valley of the shadow of death, I am not afraid of harm because you are with me;

Your staff, your staff, comfort me,

You gave me a party in front of my enemies.

You anointed my head, and my cup overflowed.

Kindness and love will accompany me all my life.

I will live in the house of the Lord,

Forever.
