What exactly does 门风帮闲 mean? The follow is an except from 《水浒传》 第二回. Based on 端王's personality traits, he could have been a Shakespeare or, at least, a Balzac, or, perhaps, under favourable circumstances, a Galileo.

I wonder what exactly 门风 in 门风帮闲 means.


  这端王乃是神宗天子第十一子，哲宗皇帝御弟，现掌东驾，排号九大王，是个聪明
  俊俏人物。这浮浪子弟门风帮闲之事，无一般不晓，无一般不会，更无一般不爱。
  即如琴、棋、书、画，无所不通，踢毬打弹，品竹调丝，吹弹歌舞，自不必说。
门风，门派的风气。
The rule of certain 帮派（gang，gaction）
