Amatungo yacu ya feza yo kwihinduranya ibirango yirata ibintu byingenzi bitandukaniye nibindi bicuruzwa kumasoko kumasoko kumasoko. Kimwe mu bintu by'ingenzi biranga amarira ari meza, bivuze ko no mu mico yo mu rwego rwo hejuru, ibi bikoresho bizakomeza kubata no gukomeza kuba indakemwa. Byongeye kandi, birahanganira cyane ubushyuhe bwo hejuru n'ubushyuhe bwinshi, buremeza kuramba no gukora mu bihe byose. Ubwanyuma, irwanya ibitidasanzwe kubihingwa byimiti, byemeza ko bikomeza kuba byiza nubwo bigaragara kuri aside na alkalis.

Muri sosiyete ya Donglai, twumva ko buri mukiriya afite ibyo akeneye nibisabwa bigomba kubahirizwa. Niyo mpamvu dutanga uburyo bwo guhitamo kugirango tumenye ko ibikoresho byacu byo kwizihiza byujuje ibyo ukeneye, byaba ubunini, imiterere, cyangwa ibikoresho bya label. Ibikoresho byacu bya feza yo kwizirikana bikwiranye no gukora ibirango bitandukanye biramba, bimwe muribyo byemejwe kugirango bifashe kurinda umutekano no kwiringirwa muburyo butandukanye bwinganda.

Waba ushaka ibikoresho byo kwifata kugirango ukoreshe kimwe-kuri kimwe cyangwa nkigice kinini cyinganda, isosiyete ya Donglai iri hano kugirango ihuze ibyo ukeneye. Hamwe nubuhanga bwacu nuburyo bwo guhitamo, turashobora kuguha igisubizo gihuza umusaruro wujuje ibisabwa byihariye, bigatuma tujya guhitamo ibicuruzwa byo kwifata. Urakoze guhitamo sosiyete ya Donglai, kandi dutegereje kuzaguha serivisi zidasanzwe nibicuruzwa.
