Rooj vag Li Qub yog siv los kaw cov dej ntws ntau dua li kev tswj kev ntws. Thaum qhib txhua lub rooj vag valve tsis muaj kev cuam tshuam nyob rau hauv txoj kev ntws ,the ntawm qhib ntws tawm hauv ib lub rooj ntws raws li lub rooj vag tsiv. Qhov no txhais tau tias tus nqi txaus tsis hloov tus ncej nrog qia taug kev. Nyob ntawm kev tsim kho, ib nrab qhib lub rooj vag tuaj yeem co los ntawm cov kua dej ntws.
