Inkunga ishobora guhindurwa ni sisitemu yigenga yigenga igizwe ninkingi zicyuma zishobora guhindurwa, imirishyo ikonjesha, inkoni itambitse hamwe na trapo, hamwe nibikoresho bike.Nkumushinga wibyuma bishobora guhindurwa, ibikoresho byubaka bya Heyuan bitanga ibyuma byuburebure buringaniye, bihindagurika cyane, byoroshye, kandi birashobora guhuza nuburebure butandukanye.Inzira nziza yo kuyikoresha nuburyo bukurikira:
Igishushanyo nogutunganya ibyuma bishobora guhinduka byoroshye.Icyuma gishobora guhindurwa hamwe na diametre zitandukanye zicyuma, uburebure bwurukuta, hamwe nuburebure bwa telesikopi birashobora gutunganywa ukurikije ibikenerwa mubuhanga, kugirango bigerweho kubika neza ibikoresho.
