Jiang’s methods are unconventional, to say the least: there are more efficient (and less smelly) ways to build strength than carrying a pig up a mountain. This method, however, is perhaps a nod to the 6th-century BCE Milo of Croton, a Greek wrestler known for training by carrying calves on his shoulders. With the rest of Jiang’s curriculum, he seems to seek to take Rin back to basics. It’s essential, his methods suggest, for Rin to learn about the history of martial arts so that she can learn not just how to fight, but how to be one with the world (he can teach her “the key to the universe”).
