Who knows when the term "Kitchen God" appeared? Does it mean informer?

The term "Kitchen God" appeared in Wei and Jin Dynasties. Its meaning is not informer, commonly known as "kitchen god", that is, kitchen god. After the appearance of Taoism, Kitchen God became the God of Life sent by the Jade Emperor to inspect people's feelings, which was widely accepted by the people.

Sui Du Taiqing's Jade Candle Collection quoted the Kitchen Book as saying, "Kitchen God, surnamed Su, named Geely, female named Bo Cheek".

The early Kitchen God originated from people's natural worship of fire. Before the Qin Dynasty, the sacrificial furnace had become one of the "Seven Sacrifices" in the national sacrificial ceremony. In the Han dynasty, the kitchen stove was listed as one of the "five sacrifices" of doctors, and the kitchen god was also personified and given new functions. The Taiping Magnolia Volume 186 quoted Huainan Wanbi Book as saying: "The kitchen god died in darkness, and the man in white was guilty."

Zheng Xuan's annotation "The Book of Rites" also said: "(Kitchen God) lives in the world, and the inspector tells it when he is young." This shows that, at least in the Han Dynasty, Kitchen God has become a fault god who reports to Heaven and speaks ill of people.
