　　The basis of the big public bus belongs to the single network body,also known as the whole network public bus.The so-called whole network public bus means that all people on the service platform are ranked above the same big network body.The people you develop are not necessarily ranked under your own account,but will be ranked under others'account.The ranking order is from top to bottom,from left to right.Generally,the direct marketing public ranking system is divided into several honor awards:direct promotion award,spot award,and exit award.With commodities as the media,select and purchase specific commodities or budget quota commodities to enter the direct marketing public ranking.
