Those people were showing their respect to Yan Fei, praising his generosity and moral character, while also expressing their 'encouragement' for Erwa's reckless demeanor in fighting and his fearless strikes.
Gangsters in the town also have hierarchies. The ones like Si Family's Brothers and Zhou Dalian from the past, including Niu Laoer who raised chickens, are experienced gangsters. Because they have some assets, it's easier for them to attract others. But those without assets are considered low-ranking, they can only depend on these top-level gangsters, following them around, doing various chores and hoping to get some benefits.
As for those like Li Fang and Chang Liang, they can't really be considered gangsters. Because they're young, they're simply loafing around with nothing to do.
So these guys definitely 'supported' Zhang Erwa hitting Zhou Dalian's cousin with a brick.
