Cov lus qhia luv luv
Qhov rooj kub nce hlau yog qhov cub tawg - rated qhov rooj uas txwv cov cua sov hloov mus rau lub sijhawm 30 feeb.
Rauv ntsuas kub ntsuas qhia qhov ntau tshaj plaws nce siab tshaj qhov tsis kub ntawm lub qhov rooj, thiab yuav yog 250 degree, lossis 650℃F.
Lub qhov rooj 250 lub qhov rooj yog qhov kev txwv ntau tshaj vim nws txwv cov cua sov hloov mus rau tsuas yog 250℃rau 30 feeb.
