普通债权可以通过通知第三债务人来实现占有的移转,从而具备了质权设定的基础,只是因为通知第三债务人无法实现公示,故需借助债权证书的交付或登记来达到公示的目的。 Ordinary claims can notify the third debtor to realize the transfer of possession, so as to have the basis for the establishment of the right of pledge. Only because the third debtor can not be notified of the publicity, so the purpose of publicity needs to be achieved through the delivery or registration of the deed of credit.
