There is a passage in "Luhuadang", which describes the old man's regret, guilt and self-blame for not completing the task satisfactorily.

"A voice like renju arrow shot through the old man's heart. He couldn't explain: how many rivers and seas he crossed, and why he didn't finish the task this time? I have no children. How lovely these two children are! Usually talk big, this time I went in with a flower-hanging person. How can I speak? This old face! "The old man is very confident and self-respecting, and he has a strong sense of responsibility. He believes that only when 100% completes the task can he fulfill his responsibilities. Listening to the groans of the injured big girl and the words of the little girl, the old man was in great pain. "A sound is like an arrow leaving the string, shooting through the old man's heart." He blamed himself for the big girl's injury and bleeding. He was extremely sad and guilty. He loves these two children too much. The children are hurt and bleeding, and his heart is hurt and bleeding. He strongly blamed himself. He felt that his commitment to the army was empty. He felt that his mistakes brought him great shame and humiliated himself. He has no face to see the psychological activities of the army's ears. I thought this old comrade was just talking. I didn't think he really did it. He did it. Seeing that he is sixty years old, I didn't expect such wisdom and courage. It's really "all that glitters is not gold". I have grown up.
