If the fire is still small and contained to one pot, it is safe to extinguish it by yourself. If it's beginning to spread to other parts of the kitchen, get everyone assembled outside and dial for emergency services. Do not place yourself in the way of harm. Call emergency services if you're too afraid to go near the fire or don't know what to do. Do not risk life and limb to save a kitchen. This is your first priority, given that a grease fire needs heat to stay alive. Leave the pot where it is, and don't attempt to move it, as you may accidentally splash burning oil on yourself or your kitchen. If you have time, put on an oven mitt first to protect your skin. Fire needs oxygen to continue, so covering it with a metal lid will essentially smother the flame. Place a metal pan lid or a cookie sheet on top of the fire. Do not use glass lids; they can shatter when exposed to fire. Also avoid using ceramic lids, bowls and plates for this purpose. These can explode and become dangerous shrapnel. Baking soda will put out small grease fires, but won't work as effectively on larger ones. It will take a large amount of baking soda to get the job done, so grab the whole box and dump it generously on the flames until they're extinguished.  Table salt will also work. If you can get your hands on that faster, use salt. Do not using baking powder, flour or anything other than baking soda or salt for this. If you have a Class B or K dry chemical fire extinguisher on hand, this can put out a grease fire. Since the chemicals will contaminate your kitchen and be tough to clean up, only do this as a last resort. However, if it's the last line of defense before the fire gets out of control, don't hesitate!

TL;DR in Vietnamese:
Đánh giá mức độ nghiêm trọng của đám cháy. Tắt bếp ngay lập tức. Dùng nắp nồi bằng kim loại đậy lên ngọn lửa. Ném muối nở vào đám cháy nhỏ. Dùng hóa chất dập lửa như phương sách cuối cùng.
