Waqtigan xaadirka ah ee Shiinaha dhexroorka weyn ee birta birta ah ee aan sinnayn, habka ugu muhiimsan ee wax soo saarka ayaa ah mid kulul iyo balaadhinta kulaylka ee birta birta ah ee dhexdhexaadka ah, kululaynta balaastigga birta birta ah ee 325mm-1220mm ugu badnaan 120mm, waxay soo saari kartaa balaadhinta kulaylka birta birta ah. Cabbirrada caadiga ah ee aan qaranka ahayn, balaadhinta kulaylka aan kala go 'lahayn waa waxa aan inta badan nidhaahno balaadhinta kulaylka, cufnaanta waa mid aad u hooseeya laakiin qandho xoog leh oo duuban oo bir ah oo leh hab ku habboon ama qaab sawir si loo ballaariyo yaraanta hababka dhamaystirka dhexroorka tuubada.In muddo gaaban ah oo dhumucdiisuna birta si ay u soo saaraan aan caadiga ahayn iyo noocyada gaarka ah ee tuubooyinka aan kala go 'lahayn, iyo qiimo jaban, hufnaan wax soo saarka sare, isbeddelka horumarinta beeraha duudduuban caalamiga ah maanta.
Dhexroor weyn oo tuubo bir ah oo aan fiicneyn oo sawir qabow ah, alaabada birta qabow-duuban, sida samaynta qabowga, daaweynta kulaylka iyo iyada oo aan si toos ah loo gaarsiin gobolka loo yaqaan xaalad qabow-duuban ama qabow-duuban.Marka la barbar dhigo gobolka kulul-rogid (fogling), saxnaanta cabbir sare ee birta qabow-jiiday (duubay) gobolka, tayada dusha wanaagsan, qallafsanaanta dusha hoose, iyo sifooyin farsamo sare leh, sababtoo ah qabow barbaro (duubay) heerka bixinta birta dusha oksaydh waa aan la daboolin, oo waxaa jira walaac badan, u nugul daxalka ama miridhku, oo sidaas birta qabow barbaro (duubay) gobolka, baakaddeeda, shuruudaha kaydinta ayaa aad u adag, guud ahaan waxay u baahan yihiin in lagu hayo bakhaarka, waana in fiiro gaar ah khasnadaha xakamaynta heerkulka iyo qoyaanka.
