Zotsogola Zatekinoloje
-Nyimbo Zanzeru:Kupita patsogolo kwaposachedwa kukuphatikiza kuphatikizika kwaukadaulo wanzeru, wokhala ndi masensa ophatikizika kuti aziwunika magwiridwe antchito monga liwiro, nthawi zogawanika, ndi kutalika kwa nthawi yeniyeni. Zatsopanozi zimathandizira pakuphunzitsa ndi kusanthula magwiridwe antchito.
Zotukuka Zachilengedwe ndi Zokhazikika
- Zipangizo zokomera zachilengedwe:Cholinga chasinthiranso ku kukhazikika, pogwiritsa ntchito zida zokomera zachilengedwe komanso njira zomangira kuti muchepetse kuwonongeka kwa chilengedwe.
