1) Ni ryari nshobora kubona igiciro?
Mubisanzwe twavuze mumasaha 24 tumaze kubona anketi yawe.Niba wihutirwa cyane kubona igiciro, nyamuneka uduhamagare cyangwa utubwire muri imeri yawe kugirango turebe ikibazo cyawe cyambere.
2) Nigute nabona icyitegererezo cyo kugenzura ubuziranenge bwawe?
Nyuma yo kwemeza ibiciro, urashobora gusaba ingero zo kugenzura ubuziranenge bwacu. Niba ukeneye gusa icyitegererezo cyo kugenzura igishushanyo mbonera hamwe nimpapuro, tuzaguha icyitegererezo kubuntu, mugihe cyose uguze ibicuruzwa byihuta.
3) Nshobora gutegereza kugeza ryari kubona icyitegererezo?
Nyuma yo kwishyura icyitegererezo hanyuma ukatwoherereza dosiye zemejwe, ibyitegererezo bizaba byiteguye gutangwa muminsi 3-7. Ibyitegererezo bizoherezwa ukoresheje Express hanyuma bigere kumunsi wakazi 3-7. Urashobora gukoresha konte yawe yihariye cyangwa ukatwishura niba udafite konti.
4) Gahunda yose ikorwa kugeza ryari?
Nyuma yo gutumiza, igihe cyo gutunganya umusaruro ni iminsi 20-25. Dukeneye iminsi 7 yo gutegura ibintu byose hanyuma iminsi 15 yo gukora.
5) Bite ho itariki yo gutwara no gutanga?
Mubisanzwe dukoresha ibyoherejwe kugirango duhindure ibicuruzwa.Ni iminsi igera kuri 7-25. Biterwa kandi na coutry hamwe nicyambu urimo.Bishobora kuba bigufi mugihe ukeneye kohereza ibicuruzwa nka Aziya. Niba haribintu byihutirwa dushobora kohereza ibicuruzwa dukoresheje indege ya Express, mugihe cyose wishyuye amafaranga yumuhanda.
6) Urimo gucuruza sosiyete cyangwa manufaturer?
Turi abanyamwuga. Ntabwo dufite uruganda rwibikoresho gusa, ahubwo dufite uruganda rwa sima.
7) Uruganda rwawe ruherereye he?
Turi mu mujyi wa Zhuzhou, Intara ya Hunan., Tungsten carbide base of China
8) Nshobora gutegereza kugeza ryari kubona icyitegererezo?
Nyuma yo kwishyura icyitegererezo hanyuma ukatwoherereza dosiye zemejwe, ibyitegererezo bizaba byiteguye gutangwa muminsi 3-7. Ibyitegererezo bizoherezwa ukoresheje Express hanyuma bigere kumunsi wakazi 3-5. Urashobora gukoresha konte yawe yihariye cyangwa ukatwishura niba udafite konti.
9) Bite ho ububiko bwawe?
Dufite ibicuruzwa byinshi mububiko, ubwoko busanzwe nubunini byose biri mububiko.
10) Kohereza kubuntu birashoboka?
Ntabwo dutanga serivisi yo kohereza kubuntu. Turashobora kugira igiciro niba uguze ibicuruzwa byinshi
