He Yahui, a young college graduate in southwestern China, didn’t follow her classmates to the city in search of a white-collar career; instead, she returned to her rural home to set up her own business – raising porcupines. He, now in her 20s, converted space in a former factory in Weiyuan county, Sichuan province, into a pen where she has successfully raised hundreds of the spiky animals for years, local news portal Scnjnews.com reported. He, who graduated from China West Normal University, makes a profit of about 300,000 yuan (US$44,000) a year from the endeavour, far more than most white-collar workers in the province. She chose to raise porcupines as there was far less competition than raising other more common species like pigs or chickens.

The famous sharp quills on their backs, which provide the animals with a very effective defence against predators, are also valuable and can be turned into medicine and fishing implements, He said.
