What kind of fairy is the grey fairy?

Grey fairy is a mouse, commonly known as mouse, and it is one of the "five immortals" worshipped by the people in China. "Five Immortals", also called "Five Masters" or "Five Immortals", respectively refer to: Fox Immortal (Fox), Huang Xian (Weasel), White Immortal (Hedgehog), Liu Immortal (Snake) and Grey Immortal (Mouse).

The origin of the grey fairy:

Rats can dig holes, climb trees, climb mountains and wade, which is extremely harmful to human beings. The worship of the mouse is because it moves in the dark day and night, making it unpredictable, so it is considered to be highly intelligent and deified. Others regard it as the god of granary, and offer it when filling the granary in China's folk festivals.

Others think that mice can predict the future, make people rich, so they are regarded as the god of wealth, hoping that they can bring treasure to their owners in the dark. China folk also imagined the world of mice as the same as the human world, and created many China folk stories and works of art, among which Yangliuqing New Year pictures, clay figurine Zhang Caisu, "Mice Marry Women" and "Mice Marry" in paper-cutting are all over the world.
