Habka Wax Soo Saarka ee Dhoobada Dabka ee La Dhufto
Xulashada agabka waa hab aad muhiim u ah, kaas oo ah isku xir muhiim ah si loo hubiyo soo saarista agabka dhoobada lagu shubo. Sida ku cad qaacidada iyo isticmaalka, agabka dhoobada ee ku habboon ee la shubo, budada, xidhka iyo waxyaabaha lagu daro ayaa la doortaa.
Isku-dubaridku waa in lagu baaro walxaha ceeriin ee la xushay iyadoo loo eegayo heerka iyadoo loo eegayo qaacidada, isla markaana si adag loo xakameeyo cabbirka isku-darka iyo budada.
Markaad walaaqayso, budada si siman u walaaq, ka dibna isku darka si siman u walaaq. Isku darka ku dar isku darka oo mar kale isku walaaq. Xakamee wakhtiga walaaqidda.
Ku rid walxaha dhoobada lagu shubay bacda tufaaxa, oo ku rid waxyaabo lagu daray iyo qalab lagu dhejiyo, ka dibna ku xidh.
Qalabka lagu shubo baakadaha waa in lagu kaydiyaa bakhaarka, taariikhdana waa in la calaamadeeyaa oo aan biyuhu celin karin.
Arrimaha u Baahan Fiiro Gaar ah oo ku Saabsan Isticmaalka Dhoobada Dabka ee La Dhufto
Si adag u xakamee isticmaalka biyaha marka aad samaynayso dhoobo ku shubaysa goobta.
Inta lagu jiro dhismaha, fiiro gaar ah u yeelo waqtiga gariirka iyo qaabka gariirka.
Xakamee habka dubista ka dib marka la shubo, mamnuuc kuleylka xad-dhaafka ah iyo ka hortagga dildilaaca jirka dhismaha.
