Mavvuno olamulira a chibayo amasintha kwambiri, poyankha mwachangu, kutsutsana msanga, kusindikiza bwino, kovuta komanso kovuta, komanso moyo wautumiki. Amagwiritsidwa ntchito kwambiri pamagetsi ndi malamulo osiyanasiyana opangira mafakitale.
Mawonekedwe:
1. Kusindikiza Kwabwino : Mphamvu yamipando yamphamvu ya chibayo imakhala ndi magwiridwe abwino, omwe amatha kupewa kutaya madzi ndikuwonetsetsa kuti dongosololi lizikhala bwino.
2. Katundu wosavuta komanso wodalirika : Mphamvu yamipando yolamulira imakhala ndi kapangidwe kosavuta, ndikosavuta kusunga ndikukhazikitsa, ndipo imakhala ndi kudalirika kwakukulu komanso kukhazikika.
3. Moyo wautumiki wautali : Mpando wa valavu ndi valavu imapangidwa ndi zida zosagwira ntchito, zomwe zimakhala ndi moyo wautali ndipo zimatha kukwaniritsa zosowa za nthawi yayitali.
Zogulitsa zazikuluzikulu zimaphatikizapo valavu yowongolera ya chibayo, valavu ya mpira, valavu yamagetsi, valavu yopendekera, yopatsa chidwi.
