Ugcino

1. Gcina phantsi kwegesi eyomileyo ene-inert, gcina i-container ivaliwe, kwaye uyigcine kwindawo epholileyo neyomileyo

2. Gcina kwindawo epholileyo, gcina i-container kude ne-container ekukhanyeni kunye nomoya, gcina efrijini. Gcina ngaphantsi kwe-4 ℃, kuphephe ukukhanya.

FAQ

1. Kuthekani ngexesha elikhokelayo lomyalelo wobungakanani bobunzima?
RE: Ngokuqhelekileyo sinokulungisa iimpahla kakuhle kwiiveki ezi-2 emva kokuba ufake i-odolo, kwaye ke sinokubhukisha indawo yempahla kwaye silungiselele ukuthunyelwa kuwe.

2. Kuthekani ngexesha lokukhokela?
Impendulo: Ngexabiso elincinci, iimpahla ziya kuthunyelwa kuwe ngaphakathi kwe-1-3 yeentsuku zokusebenza emva kwentlawulo.
Ngobungakanani obukhulu, iimpahla ziya kuthunyelwa kuwe ngaphakathi kwe-3-7 yeentsuku zokusebenza emva kwentlawulo.

3. Ngaba kukho nasiphi na isaphulelo xa sifaka iodolo enkulu?
RE: Ewe, siya kubonelela ngesaphulelo esahlukileyo ngokweodolo yakho.

4. Ndingayifumana njani isampuli ukujonga umgangatho?
RE: Emva kokuqinisekiswa kwexabiso, unokufuna isampuli ukujonga umgangatho kwaye singathanda ukubonelela ngesampuli.
