It’s a tradition that dates back hundreds of years, where two stallions fight over a female to ring the Chinese new year. And when it’s the Year of the Horse, the fights are considered to be even more significant. They’re held in small villages across southern China and have been condemned by animal rights groups, including Hong-Kong based Animals Asia. But those who participate in the events defend the fights and insist they take care of the animals.
