The paper shows a different approach based on a sales theory which is characterised by human-centeredness.The CRM(customer relationship management) software's shortage is pointed out.An idea is demonstrated: all selling is to Key People(KP) and Core Opinion Leader(COL),the key of selling is the integrated virtual product which is a set of deliverable buying points and selling points that the individual KPs and COLs accept according to their individual views on criteria.A sales process may be monitored by index such as customer relating status,customer attitudes toward buying points,customer publicly demonstrated behaviors relating the selling points,then we may have a relating information table and its main process.Finally,the concept of customer relationship chain management is discussed.
