Now a cult obsession thanks to Hong Kong horror movies of the 1980s and 1990s, the legend of the hopping vampire was first detailed in a series of supernatural reflections compiled between 1789 and 1798 by Ji Xiaolan (also known as Ji Yun) and collected posthumously in an 1800 volume entitled Yuewei Caotang Biji (閱微草堂筆記) – it’s English-language translation being the rather beautiful Random Notes at the Cottage of Close Scrutiny.
