Alualu i luma le vevela vevela togafitiga tekonolosi mo le tuuina atu o le gaosiga | Shangdong YeuELng

Vevela Togafitiga faʻatonutonu o loʻo faʻatautaia o le faʻaaogaina o galuega e aofia ai le faʻafesoʻotaʻiga o le lelava soifua O le gaosiga a le aso nei e manaʻomia ± 3 ° C HE HACERC ma le Taualumaga Capapunt Cpk≥1.33. CORE faasologa: O le amoina o le a le masani ai → quanching → maualalo-vevela ita ita → stabilization.
