Microwave ovens emit microwaves through magnetrons. Microwave is a kind of high-frequency electromagnetic wave with a frequency of 2450 MHz, which has strong penetration. It can penetrate plastic, glass, ceramics and food, making the water molecules inside the food vibrate violently and generate heat. The inside and outside of the food generate heat at the same time, so the heating speed is very fast and the efficiency of converting electric energy into heat energy is very high.

China sausage was produced before the Northern and Southern Dynasties, and it was first seen in the "enema method" in Qi Yaomin's Book of the Northern Wei Dynasty, and its method has been passed down to this day. China sausage can be stored for a long time without starch and eaten after cooking. It tastes delicious, full-bodied and has a long aftertaste. It is far superior to other countries' enema products. It is one of the traditional foods in China and enjoys a high reputation at home and abroad.
