"Get lost, don't meddle in other people's affairs, or I'll beat you up too." The youth saw Yin Xiaofan protecting the child and spoke angrily.
Yin Xiaofan frowned, perceiving the youth's volatility and deeming him to be a rather unsavory character.
"As long as I'm here, I won't allow you to bully children. You better leave now!" Yin Xiaofan said firmly.
"You're asking for it." Not expecting Yin Xiaofan to be so determined to interfere, the youth's temper flared and he took a swing at Yin Xiaofan.
He threw a punch at Yin Xiaofan, seemingly intending to hit him as well.
Seeing that the youth was quick to violence, Yin Xiaofan swiftly dodged to the side and then executed a grappling move, seizing the young man's arm, twisting it behind him, and kicking him in the shin.
The youth fell to his knees, struggling to break free, but Yin Xiaofan's hold was too strong.
"Ow! That hurts, let go!" The youth, though looking formidable, was not much of a fighter in reality.
