l UNC Threads : Inozivikanwa nekukasira kwadzo, tambo idzi dzakakosha mukuvaka, muchina unorema, uye zvigadzirwa zvemazuva ese kuti zvive nyore kushandisa uye kusimba.
Kusarudza shinda chaiyo - UNF kana UNC - inodzika ku:
l Kunzwisisa Chikumbiro : Izvo chaizvo zvinodikanwa zvepurojekiti yako, ingave yakanyanya kurongeka kana kusimba, zvinotungamira sarudzo yako.
l Indasitiri Maitiro : Kuziva nezve maindasitiri magungano kunobatsira mukuita sarudzo ine ruzivo.
l Kugarisana : Kuve nechokwadi chekuti tambo, mabhaudhi, uye nzungu zvaunosarudza zvinoenderana kwakakosha pagungano rakabudirira.
Mashinda anogona kunge ari madiki, asi maitiro awo akakura. Kubva mundege inokwira pamusoro pedu kusvika kumidziyo yemagetsi yatinoshandisa mazuva ese, UNF neUNC tambo dzinobata nyika yedu pamwechete. Saka nguva inotevera paunenge uchishanda pachirongwa, funga kune aya magamba madiki. Sarudzo yako pakati peUNF neUNC inogona kuita mutsauko wese mukusimba, kurongeka, uye hupenyu hurefu hwechisikwa chako.
