Ukwelashwa kwangaphambi kokumbozwa kungummeleli ojwayelekile wezinhlelo zokusebenza zombhobho. Imibhobho yangaphambi kokumboza esiyiklama futhi siyenze inokusebenza okuhle kakhulu futhi ingasusa kalula amabala kawoyela, ukugqwala noma amakhemikhali ebusweni bento. Futha ngaphambi kokumboza ukumboza Isinyathelo esibalulekile kule nqubo, kubaluleke kakhulu ukukhetha umlomo wombhobho onekhwalithi ezinzile.

Imibhobho esemzimbeni yethu inezici zokufafaza okufanayo, umthelela oqinile, nokonga amanzi, futhi inezinhlobo ezahlukahlukene zezicelo embonini yokumboza yomhlaba. Ukukhetha imibhobho esemibalabala esezingeni eliphakeme kakhulu kungakwenza wenze okuningi ngokuncane.
