Why does Lu 'an Forum like to attack Huoshan people?

Look clearly, where are the people who attacked Huoshan people in the forum? They are all Shucheng people! Shucheng people don't admit that they are from Lu 'an, but insist that they are from Hefei, and Hefei doesn't want them, so they are shameless enough to post them in Hefei. Shucheng had Houdun Beer and Jinlong Beer at the earliest, but now they can't compete with Yingjia Group. It may be the abnormal revenge that led them to attack the Huoshan people.
