Ndodo ya ku Poland

Kufotokozera Kwachidule:

Ndodo yaku Poland ndi mtundu wa ndodo yapadera yoyamwa yolumikizidwa ndi ndodo yoyamwitsa ndi hanger. Ili pamwamba pa ndodo yoyamwitsa, yomwe imayenera kupirira mphamvu zambiri, kotero ndi kukula kwakukulu ndi chitsulo chapamwamba kuposa ndodo ya sucker, ndipo pamwamba pake ndi yosalala kwambiri.

1. Ndodo ya ku Poland ndi mtundu wa ndodo yapadera yoyamwa yolumikizidwa ndi ndodo ya sucker ndi hanger. Ili pamwamba pa ndodo yoyamwitsa, yomwe imayenera kupirira mphamvu zambiri, kotero ndi kukula kwakukulu ndi chitsulo chapamwamba kuposa ndodo ya sucker, ndipo pamwamba pake ndi yosalala kwambiri.

2. Ntchito yayikulu:

Kuphatikizidwa ndi kulongedza katundu mu bokosi lonyamula kuti musindikize bwino ndikupewa mafuta, gasi, kuwululidwa kwamadzi.

Cholumikizira pakanthawi pakati pa ndodo yoyamwitsa ndi hanger ya mutu wa bulu

Kumaliza kuyesa kwachiwonetsero.

Malizitsani ntchito zosiyanasiyana zamutu, monga kugunda kwa pampu, kuwongolera makonzedwe a pampu.
