| Mulingo wa IPC ukuwonetsa mulingo wamtundu wamtundu uliwonse wa bolodi yosindikizidwa, ndipo opanga magetsi ena amatha kupanga IPC yoyamba ndi yachiwiri. M'kanthawi kochepa, sipangakhale kusiyana kowonekera, koma pakapita nthawi, nkhani za khalidwe lazogulitsa zimakhala zodziwika kwambiri. Ngati katundu wanu ndi wamakampani ndipo mumayang'ana kwambiri pamtengo wanthawi yayitali, chonde onetsetsani kuti mwasankha mulingo wapamwamba kwambiri.
