Lesi sixhumanisi sinezinhlobo ezimbili zesikhwama (isikhwama esinezinhlangothi eziyisishiyagalombili, isikhwama esizisekelayo). Lezi zinhlobo ezimbili zezikhwama zithandwa kakhulu phakathi kwezikhwama zokudla. Basebenzisa ubuchwepheshe obuyinhlanganisela eminingi futhi bame kahle, okuvumela ukuboniswa kweshalofu futhi kwenze uphawu lube luhle kakhulu. Ibukeka isezingeni eliphezulu futhi igqamile, inomphumela omuhle wokuvala uphawu.
Isikhwama esinoziphu singavalwa ukuze siphinde sisetshenziswe.
