Ngokuvamile kunezinhlobo ezimbili zemibhobho yokuhlanza amathangi aphezulu. Owokuqala ngumbhobho wokuhlanza ithangi ongaguquki. Siqukethe ingxenye enkulu yomzimba enkulu lapho kufakwa khona imibhobho eminingi yesigaxa egcwele ngokuhambisana nemithetho. Imibhobho iqondiswa ekhoneni elibekiwe. Futha uketshezi nxazonke ukuhlanza ingaphakathi lethangi. Inzuzo yayo ukuthi ingakhiqiza indawo yokufafaza embozwe umfaniswano. Ngenxa yokwakheka okungaguquki, akulula ukulimala, futhi noma ngabe imbhobho encane yonakele, ingashintshwa ngqo. Okubi ukuthi yiyona kuphela engahlanza amathangi amancane. Lapho ububanzi bethangi bukhulu kakhulu kunobubanzi bombhobho, umthelela wesifutho uzobuthaka futhi umphumela wokuhlanza uzokwehla.

Ukuze sikwazi ukubhekana nezidingo zokuhlanza zamathangi amakhulu, sakha futhi sakha umbhobho wokuhlanza indiza ojikelezayo. Kubonakala ngokukwazi ukukhiqiza amandla amakhulu omthelela futhi usebenzise amandla okusabela omthelela wamanzi ukusunduza umbhobho ukuze ujikeleze. Lapho umbhobho uzungeza isikhathi esithile, ithangi Udonga lwangaphakathi lwethangi luyogezwa luhlanzeke ngomfudlana ketshezi onengcindezi ephezulu.

Uma ufuna ukwazi kabanzi mayelana nolwazi lobuchwepheshe we ephezulu ingcindezi ithangi yokuhlanza umlomo wombhobho, sicela ukhululeke ukuxhumana nathi.
