Ntchito yathu yachitsulo imagwiritsa ntchito njira yodzitcherera kawiri konse, kuonetsetsa kuchuluka kwakukulu komanso mtundu uliwonse. Njirayi imaphatikizapo kuwotcherera mapaipi achitsulo kuchokera mkati ndi kunja, ndikupanga mgwirizano wamphamvu. Zotsatira zake ndi chinthu chomwe chimayamba kuwononga kwambiri komanso choyenera mafakitale osiyanasiyana komanso ntchito zomanga.

Kaya limagwiritsidwa ntchito ngati maziko a polojekiti kapena gawo la pomanga kapena gawo la zotchingira, ziphuphu zathu, ziphuphu zathu zimapangidwa kuti zithetse mavuto ovuta kwambiri. Amapereka ntchito yodalirika komanso kukhazikika kosatha, kumawapangitsa kukhala abwino kwa ntchito zosiyanasiyana ndi zomangamanga.

Mwachidule, kuzizira kwathu kunapangidwamapaipi gasi, zopangidwa kuchokera ku zitsulo chimodzi ndipo zimapangidwa pogwiritsa ntchito njira yotentha yotentha kwambiri, ndi njira yodalirika komanso yapamwamba kwambiri yogwiritsira ntchito mapulogalamu osiyanasiyana.
