A jiangshi, also known as a Chinese hopping vampire or hopping zombie, is a type of reanimated corpse in Chinese legends and folklore. The characters for "jiangshi" are read geung-si in Cantonese, cương thi in Vietnamese, gangsi in Korean, and kyonshī in Japanese. It is also known as phi dip chin in Thai, hantu pocong in Malay, and vampir cina in Indonesia. It is typically depicted as a stiff corpse dressed in official garments from the Qing Dynasty, and it moves around by hopping with its arms outstretched. It kills living creatures to absorb their qi, or "life force", usually at night, while during the day, it rests in a coffin or hides in dark places such as caves. Jiangshi legends have inspired a genre of jiangshi films and literature in Hong Kong and East Asia.
Generally, a jiangshi's appearance can range from unremarkable (as in the case of a recently deceased person) to horrifying (rotting flesh, rigor mortis, as with corpses that have been in a state of decay over a period). The Chinese character for "jiang" in jiangshi" literally means "hard" or "stiff". It is believed that the jiangshi are so stiff that they cannot bend its limbs and body, so it has to move around by hopping while keeping its arms stretched out for mobility. Jiangshi are depicted in popular culture to have a pape talasmanr (with a sealing spell) attached onto and hanging off the forehead in portrait orientation, and wear a uniform coat-like robe and round-top tall rimmed hat characteristic of a mandarin (Chinese official from during the Qing dynasty). A peculiar feature is its greenish-white skin; one theory is that this is derived from fungus or mould growing on corpses. It is said to have long white hair all over its head and may behave like animals. The influence of western vampire stories brought the blood-sucking aspect to the Chinese myth in more modern times in combination with the concept of the hungry ghost, though traditionally they feed solely on the qi of a living individual for sustenance and in order to grow more powerful.
