When the other children saw, they were closer to Jinguan anyway, plus the adults in the family had all instructed them to maintain a good relationship with the Wang Family and not to offend them.
But nothing was said about not offending the Song Family. On the contrary, they were told that the Song Family were no good, had a grudge against Lord Song, and they should never play with the Song Family's children, or they'd be beaten when they got home.
Thinking about it this way, with Jinguan being generous, the Wang Family's food being better and more plentiful than others, and occasionally bringing some out for the village children to taste, they couldn't help but side with Jinguan.
So they crowded forward, supposedly to stop the fight, but actually they just pulled the other Song Family kids away, leaving Jinguan to hold down the Song Family boy and beat him.
Jinguan didn't stop until the Song Family boy was crying for his parents and begging for mercy.
