He had guarded the Tang Dynasty all his life, guarding Yanmen in the ice and snow. As a member of the Cangyun Army, he was worthy of the soldiers and civilians. As a human being, two innocent people died because of him and for him.
Someone asked him that day if he regretted it.
He answered, no
Ask him, are you still guarding?
He replied, keep
Ask, why
Answer, defend the city, defend... Not return to others
