Mo Yan, winner of the 2012 Nobel Prize in Literature, has a deft way with similes: salty, sometimes gross, usually unexpected. Comparing women’s breasts to “ripe mangoes” is almost a cliché, but to describe the nipples as “rising gracefully, like the captivating mouths of hedgehogs” is arresting. Passengers disembarking from a train do so “like beetles rolling their precious dung.” A rich meal of pork lies on a man’s stomach, “churning and grinding like a litter of soon-to-be-born piglets.”

What gives Mo Yan’s novels their highly idiosyncratic tone is the combination of a great literary imagination and a peasant spirit. Howard Gold­blatt’s translations catch this atmosphere brilliantly. The prose reads well in English, without losing a distinctly Chinese feel, but it is very far from the classical Chinese tradition. There is nothing mandarin, or even urbane, about Mo Yan’s work. He has retained the earthy character of rural Shandong, where he grew up in a farming family.

Like most of his stories, both “Sandalwood Death” and “Pow!” are set in a rustic place resembling Mo Yan’s native village in Gaomi County. Of “Sandalwood Death,” he has written that it might be less suited to sophisticated readers than “to hoarse voices in a public square, surrounded by an audience of eager listeners.” In fact, it is artfully written in the style of a local folk opera called Maoqiang, now almost defunct. One of the main characters is an opera singer. The rhythms, idioms and narrative techniques of ­Maoqiang are ­woven into the text in a seamless way that only a master storyteller can pull off. The art of telling stories is actually the main theme of both novels.

The narrator of “Pow!,” Luo Xiaotong, is a young man who has a horror of growing up, of entering the corrupt adult world where the powerful prey on the weak. As Mo Yan explains in his afterword, Luo is the reverse of little Oskar in Günter Grass’s “Tin Drum,” the boy whose body stops growing even as his mental age progresses. Luo has a child’s mind in a grown-up body. He is the sort of wise simpleton, a kind of Chinese Soldier Schweik, that often turns up in Mo Yan’s novels. When Luo looks at Aunty Wild Mule, his father’s mistress, he feels “like a boy of 7 or 8,” and yet “the pounding of my heart and the stirrings of that thing between my legs declare to me that I am that child no longer.” By observing the adults, Luo realizes that sex can lead people into some very dark places. And so he clings to a kind of innocence. But, as so often happens when the strain of growing up in a corrupted world becomes intolerable, innocence explodes in an act of extraordinary violence. “Pow” can mean two things: It is the bang of an old Japanese Army mortar, used by Luo to blow the adult world to smithereens; it also means to brag, to tell stories, and even, in Beijing slang, to have sex.
