Ibishishwa muri rusange bifite ikibazo cyo gusya, hanyuma ibishishwa byiza byambarwa igihe kinini mubyukuri, hazabaho ibibazo runaka byo gusya, kuki ibishishwa byibi bikoresho byoroshye gusya?
1. ibintu fatizo bifatika: uko ubuziranenge bwibikoresho fatizo byubwoya buringaniye, niko bwiza, ubwiza bwikigereranyo, ubunini bwa curl nibyiza, ukumva byoroshye, ariko byoroshye guhuzagurika, gusya.
2. imiterere yimyenda yimyenda iratandukanye (urushinge ruringaniye, Yuan Bao, Yuan Bao inshuro ebyiri, nibindi), ubucucike butandukanye (bworoshye, bufunze) nabwo buzatanga impamyabumenyi zitandukanye za fonctionnement, Ikigo cya leta gishinzwe kugenzura tekiniki ya leta yo gupima ibinini gishingiye ibirundo bitandukanye (kubara) bikozwe mubisobanuro byihariye byerekana ubucucike, imiterere ya tissue yicyitegererezo mugihe cyagenwe mugupima agasanduku, hanyuma usuzume urwego.
3. kwambara hamwe nibintu bitandukanye (byoroshye, bikabije) guhuza, bizanatanga ibyiciro bitandukanye byo guteranya ibintu, amaboko, imifuka nibindi bice byo guterana amagambo nabyo byoroshye gusya.
4. uhereye kubikorwa: niba impinduramatwara irekuye, ikirundo ni kinini kandi kibyibushye, umurongo uruzuye, ariko byoroshye gusya, ibinyuranye ni uguhinduranya birakomeye, bizatakaza uburyo bwikirundo, nkumugozi.
