Munguva yakareba yapfuura, takatora matafura ekushandura ekunze kuenda kune echiChinese, asi panguva yekushandiswa, nekuda kwemakemikari ari muzvinhu, tekinoroji yekugadzirisa, saizi yejometri yemuenzaniso nezvimwe zvinhu pamwe nekururama kwezvishandiso zvekuyera munyika dzakasiyana, hukama hwekushandura kuomarara nesimba kuti hugadzire hwaro uye nzira dzekugadzirisa data dzakasiyana, takaona kuti pane musiyano mukuru pakati pemhando dzakasiyana dzekushandura. Pamusoro pezvo, hapana mwero wakabatana, nyika dzakasiyana dzinoshandisa tafura yakasiyana yekushandura, zvichiunza kuvhiringidzika mumhando dzekushandura kuomarara nesimba.
Kubva muna 1965, China Metrology Scientific Research nedzimwe nzvimbo dzakagadzira Brinell, Rockwell, Vickers uye zvibodzwa zvesimba reRockwell zvichibva pakuongorora kwakawanda, kuti vaongorore hukama huripo pakati pekuoma kwakasiyana-siyana nesimba resimbi dzesimbi, kuburikidza nekusimbiswa kwekugadzirwa. Vakagadzira "tafura yedu yekushandura kuomarara kwesimbi nhema" yakakodzera simbi 9 dzakatevedzana uye pasinei negiredhi resimbi. Mubasa rekusimbisa, mayuniti anopfuura zana akabatanidzwa, huwandu hwesampuru dzinopfuura 3,000 dzakagadziriswa, uye data rinodarika 30,000 rakayerwa.
Ruzivo rwekusimbisa rwakagoverwa zvakaenzana kumativi ese ekongiri yekushandura, uye mhedzisiro yacho inoenderana nekugoverwa kwakajairika, kureva kuti, matafura aya ekushandura anoenderana nechokwadi uye aripo.
Matafura aya ekushandura akaenzaniswa pasi rose nematafura akafanana ekushandura enyika gumi, uye kukosha kwekushandura kwenyika yedu kunenge kuri avhareji yemitengo yekushandura yenyika dzakasiyana-siyana.
