The term "Chinese weasel" refers to a small mammal found in China known for its agile and ferocious nature. It is also known by several other names in the region, including the Yellow-bellied weasel, Mandarin weasel, and Cantonese weasel. Its scientific name is Mustela sibirica, and it is closely related to the European weasel. Despite being called a weasel, it is not a true weasel as it belongs to the genus Mustela, which also includes stoats, ferrets, and minks. The Chinese weasel is an important predator in the ecosystem as it preys on small rodents, birds, and insects.
