That crazy mule was one of our favourite topics of conversation. Skinny as a rail, the indentations above both eyes were so deep they could accommodate hen’s eggs. Its eyes emitted a sorrowful gaze, as if it were about to howl. How a skinny animal like that could exert such strength was a mystery. We were talking about that as we drew up to the mule. Wang Jiao stopped shovelling coal and glared menacingly, backing us up terrified. The pile in front of the school kitchen grew higher and higher, the load of coal on the cart kept getting smaller. We sniffed in unison at the strange aroma in the air, a bit like burning pine or roasting potatoes. Our sense of smell drew our gaze to the pile of glistening coal as Wang Jiao flicked the reins and drove his cart out of the schoolyard. This time we didn’t chase it out of the yard, as we usually did, even risking the bite of Wang’s whip when we tried to climb aboard to satisfy our desire for a ride. No, we kept our eyes glued to the pile of coal as we shuffled forward. Old Wang, the school cook, wobbled over with two buckets of water on his shoulder pole. His daughter, Renmei, was also a classmate who, much later, would become my wife. She was one of the rare children not burdened with the name of a body part, and that was because her father had attended school. As the one-time head of a commune animal-husbandry station, a careless comment had cost him his job and sent him back to his village. He observed us with a wary eye. Did he think we were planning to raid his kitchen? Go on, you little shits, get out of here! There’s nothing here for you to eat. Go home and suck your mothers’ teats. We heard him, of course, and even considered what he’d said. But he was just mouthing off. Already seven or eight years old, we were way past nursing at our mothers’ breasts. Even if we hadn’t been, our half-starved mothers, with their flattened chests, had nothing to give us. But we weren’t interested in arguing with Old Wang. Instead, we stood in front of the pile of coal, heads down and bent at the waist like geologists who have discovered an unusual rock formation. We sniffed the air like dogs searching for food in a rubbish pile. At this point I need to first thank Chen Bi and then Wang Dan. It was Chen who first picked up a chunk of coal and sniffed it, crinkling his brow as if pondering a weighty question. His big, high-bridged nose was a source of laughter for us. After a thoughtful pause, he smashed the coal in his hand against a much larger piece, like shattering glass, releasing a strong aroma into the air. Both he and Wang Dan picked up shards. He licked his to taste it and rolled his eyes as he looked our way. She copied him by tasting hers and looking our way. They exchanged a glance, smiled, and as if on cue, cautiously took small bites; they chewed briefly before taking bigger bites and chewing like crazy. Excited looks burst onto their faces. Chen Bi’s big nose turned red and was beaded with sweat. Wang Dan’s little nose turned black with coal dust. We were entranced by the sound of coal being chewed and shocked when they swallowed it. They’d actually swallowed coal! It’s good, guys, he said softly. Eat up, big brother! she cried out shrilly. Wang Gan picked up another piece and really started to chew, while she grabbed a large chunk and handed it to him. So we followed their lead, smashing the coal into smaller chunks and nibbling it at first to see how it tasted. Though it was sort of gritty, it wasn’t half bad. Chen Bi picked up a large chunk. Eat this kind, guys, he said helpfully, it tastes the best. He pointed to some slightly transparent, amber-like pale yellow coal. That was the source of the pine aroma. From our nature study class we’d learned that coal formed over millennia from buried forests. Our teacher for that class was our principal, Wu Jinbang. We hadn’t believed him or what the textbook said. How could green forests turn into black coal? We’d thought he and the textbooks were lying. But the smell of pine trees changed our minds. Our principal and the textbook were telling the truth. All thirty-five students in our class, except for a few absent girls, picked up chunks of coal and started chewing, crunching away, slightly mysterious looks of excitement on our faces. It was like improvisational theatre or a strange game. Xiao Xiachun (Lower Lip) turned a piece of coal over and over in his hand, but chose not to eat it, a superior look on his face. He didn’t eat it because he wasn’t hungry, he said, and that was because his father was the commune granary watchman.
