Jiangshi (Chinese)
A jiagshi also known as a Chinese hopping vampire, is a type of reanimated corpse in Chinese legends and folklore. 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. Although the pronunciation of jiangshi varies in different East Asian countries, all of them refer to the Chinese version of vampires.
