What words are engraved on the back of Li Dazui?

Li Dazui's back is engraved with the words "Hero forgives". These words were tattooed by Li Dazui's mother. Speaking of frontal battlefield, as long as you meet the enemy and show them these four words, you will surely survive.

In the fourth episode of Wulin Biography, Li Dazui's mother had a relapse. In order to reassure her mother and make her happy, Li Dazui lied that she had won the first prize just to make her happy. Li Dazui's mother thought her son was going to the front. She also learned the way Yue Fei's mother tattooed her son's back, tattooed four words on his back, and showed them off. As long as you meet the enemy, you can show them, and they will be scared out of their wits.

At first, no one knew what these words were. Later, Guo Furong and Li Dazui tore off his coat in an argument. We saw the words "Hero forgives" on Li Dazui's back. At first, we burst into laughter, but thinking of the mother's concern for her son's life, we wanted him to live. In any way, we all lament the greatness of maternal love.
