Nakuba zinkulu njengesitimela esisheshayo, izindiza, amarobhothi, ezincane njengezingcingo eziphathwayo, amakhamera, amakhompyutha, imishini yezokwelapha, izikulufo zibalulekile. Ngaphezu kwale mikhiqizo zidinga izikulufo, ngisho nezinye iziguli zidinga izikulufo ezikhethekile ezifakwe emzimbeni ukuze zelashwe izimo ezithile. Izikulufo ezimelelwa izikulufo azizona nje izinto ezincane ezifinyeleleka empilweni yabantu, zichazwa nangokuthi “ithuluzi elihle kakhulu lenkulungwane yesibili yeminyaka kusukela enkathini yabantu.”

Njengethuluzi elibalulekile, uma kunenkinga ngokuhlinzekwa kwezikhonkwane, ngokungangabazeki kuzoba nomthelela omkhulu emabhizinisini angaphansi komfula. Njengamanje, isimo sobhubhane sisesesigabeni sokubhekana naso, futhi isidingo sezinhlobo ezahlukene zemishini emelelwa yimishini yezokwelapha kanye nemishini ehlobene nemaski sikhulu. Isibonelo, inkampani eNingbo ithole i-oda lesethi yokususa umswakama ejikelezayo eyenziwe ngokwezifiso ngumkhiqizi wezinto zokusetshenziswa zemaski ze-workshop yokucubungula i-electret engalukiwe eDalian. Izikulufo zokuzithinta kanye nezinye izikhonkwane.
