Ubwino Wabwino waku China Chitoliro Chokhazikika Chokhazikika cha Carbon Chitsulo Chopanda Msokonezo
Kampani yathu ikufuna kugwira ntchito mokhulupirika, kutumikira kwa makasitomala athu onse, ndikugwira ntchito muukadaulo watsopano komanso makina atsopano nthawi zonse a Chitoliro Chopanda Chopanda Chitsulo, Ngati mukuyang'ana kwamuyaya Zabwino kwambiri pamtengo wapamwamba wogulitsa komanso kutumiza munthawi yake. Lankhulani ndi ife. Kampani yathu imatsatira malamulo ndi machitidwe apadziko lonse lapansi. Timalonjeza kukhala ndi udindo kwa abwenzi, makasitomala ndi onse othandizana nawo. Tikufuna kukhazikitsa ubale wautali komanso ubwenzi ndi kasitomala aliyense padziko lonse lapansi pamaziko a zopindulitsa zonse. Tikulandira mwachikondi makasitomala onse akale ndi atsopano kudzayendera kampani yathu kukakambirana za bizinesi.
Mwachidule
Kugwiritsa ntchito
Amagwiritsidwa ntchito makamaka pazigawo zamphamvu ndi zokakamiza, komanso pazolinga zonse za nthunzi, madzi, gasi ndi mapaipi amlengalenga.
