Fu Chong, also known as Fan Bi Chong (反鼻虫 fǎn bí chóng) or Fu She (蝮蛇 fù shé), are giant poisonous snakes from Chinese mythology that are said to be able to grow to over 50kg. Their skin is like a red and white ribbon, and they have a spike on the end of their nose.
Fu Chong were first mentioned in the Classic of Mountains and Seas and unlike the majority of beasts and birds cited in the text which can only be found on certain mountains or in certain bodies of water, Fu Chong are located on numerous mountains.
