The son of the Prefect had his own entourage of little followers. When Yuan Wang made the first move, they all ganged up on him, beating him. Upon seeing this, Yuan Wang's brother Yuan Xi rushed to save his older brother, and then a melee ensued.
It's true that they fought the Prefect's son, but in reality, the two brothers took more of a beating.
After that, the Yuan brothers were locked up in the County Governor's Office jail, and the Lord County Magistrate hasn't yet decided what to do with the case. There's still no news from the Prefectural City.
Yuan Cheng sought help far and wide, using all the connections he had, but his restaurant was no longer sustainable and he had previously offended the Lord County Magistrate. No one dared to speak up for him.
