Huo Qihan said this very tactfully and phrased it in a way that the person who had made the first move had beaten up the other until he had to be admitted to the hospital. If ordinary people heard this, they would automatically favor the injured party.
He had vaguely spoken about Su Yayan beating Huo Shaofeng but glossed over the reason why Su Yayan had fought with Huo Shaofeng or why she even beat him in the first place.
Taken out of context vaguely and tactfully, Huo Qihan seemed to imply that Su Yayan beat Huo Shaofeng because she was angry that he had cheated on her.
What Huo Shaofeng did before was wrong, but he was beaten and scolded for his misdoings.
They had also ordered him to break up with that woman, and if the Su family continued to pursue the matter, they would be perceived as overly aggressive.
