Viet's were the original hydro-house asians,hence the nail-bars and cash-in-hand businesses,chinese have only moved onto that scene in the past 3-4 years?Average chinese IS indeed insular,thats fact BUT they arent all crims,thats also fact,very industrious people,family oriented,if they can evade tax they will indeed do so,not all gamble but lots do,its the asian way,I lived over there for years,and know a large number of chinese and other asians around london,got a number as good friends.
