琉球　在海東南。自福建梅花所開漾。順颷利舶七日可至。其俗以盈虛為晦朔。以草木為冬夏。人皆去髭黥手。羽冠毛衣。無禮節好剽掠。至此遣子弟來學。夷習稍變。奉正朔設官職。被服冠裳。陳奏表章。著作篇什。有華風焉。

Ryukyu: Located in the southeast seas. Setting sail from Meihuasuo in Fujian, one can arrive in seven days with favorable winds and good ships. Their custom takes waxing and waning as the month's end and beginning, and uses plants and trees to mark winter and summer. The people all shave their beards and tattoo their hands, wearing feather caps and fur garments; they lack etiquette and are fond of plundering. At this point, they sent sons and younger brothers to study, and their barbarian customs slightly changed: they adopted the calendar, established official posts, wore robes and caps, presented memorials and petitions, and composed literary works, exhibiting the style of China.
