Chollima (Korean)
The qianlima; also chollima or cheollima in Korean, and senrima in Japanese; lit.?'thousand-li horse') is a mythical horse that originates from the Chinese classics and is commonly portrayed in East Asian mythology. The winged horse is said to be too swift and elegant to be mounted by any mortal man and is named after its ability to travel one thousand li in a single day.
Beginning around the 3rd century BCE, Chinese classics mention Bole, a mythological horse-tamer, as an exemplar of horse judging. Bole is frequently associated with the fabled qianlima "thousand-miles horse", which was supposedly able to gallop one thousand li (approximately 400 km) in a single day.
