校长没听说过《蜻蜓海》，但认识其中主角的原型人物Mwamaka Sharifu，“她就是我表姐，当然这座岛上的居民或多或少都有些亲戚关系”。Sharifu的DNA检测出中国血统，并获得奖学金赴南京留学。因为当地民间口述历史中，有过郑和船队的沉船幸存者与岛民通婚的传说，Sharifu也就被媒体塑造为郑和船队的后裔。小说就是根据这些真假参半的故事进行虚构，将其中的女主角，比喻为一只努力扇动翅膀、远渡重洋、改变命运的蜻蜓。

When new employees come to work at the Boeing production facility in Everett, Washington, one of their first stops is often an exhibition at the company’s Safety Experience Center. It opens on a sombre note: a memorial for famous air disasters, including the successive crashes of two 737 MAXs, in 2018 and 2019, in the Java Sea and Ethiopia. Then, gradually, the tone grows more hopeful. At Boeing, as throughout the aviation industry, disasters led to innovations. Oxygen masks and electronic anti-skid brakes were introduced in the nineteen-sixties, along with bird cannons at airports, to shoo off Canada geese and fellow-fliers. Overhead bins got latched doors that same decade, to keep luggage from toppling onto passengers’ heads. Satellite communication came along in the seventies; automated flight-management systems, capable of plotting a plane’s course, speed, and altitude, in the eighties. Radar systems got more accurate; planes grew stronger, sleeker, and more flexible. Pilots got better at skirting turbulence—or, if they couldn’t, at slowing down and “riding the bumps.”
