Fan Chuo,
Translation:Manshu — Chapter 9
“ It is suspected that in the Nanzhao section of the New Book of Tang that 朱 ("pearl") is recoded in error and should be 光 ("shining") .) with rhinoceros horns and copper braids, [4] go barefoot, and move so rapidly [5] that it is as if they are flying. 每百人,羅苴佐一人管之。 For every hundred men there is one Luójū (羅苴; lit. 'Hemp Gatherer') . 負排,又從羅苴中揀入,無貝數。 Men do not hold military rank-and-file formation, but rather attack in a wedge behind their commanding Luójū (羅苴) . ”
