FAQ

Q1: Kodi mukuchita malonda ndi kampani kapena wopanga?

A: Ndife fakitale.

Q2: Kodi nthawi yanu yobweretsera ndi yayitali bwanji?

A: Nthawi zambiri zimakhala masiku 5-10 ngati katunduyo ali m'sitolo. Kapena masiku 30 ngati katunduyo alibe, zimatengera kuchuluka kwake.

Q3: Kodi mumapereka zitsanzo? Kodi ndi zaulere kapena zowonjezera?

A: Inde, tikhoza kupereka chitsanzocho kwaulere ndi mtengo wa katundu wolipidwa ndi kasitomala.
