交趾

Traditionally said to have been a placename from the time of the sage-king Yao. In fact, an early form of the name Giao Chỉ seems to have been used by the native states for the area around the Red River delta prior to the Chinese conquest.

The Book of Rites noted that the southern barbarians (Man) had crossed toes (交趾).

南方曰蠻，雕題交趾，有不火食者矣。 [Classical Chinese, trad.]

南方曰蛮，雕题交趾，有不火食者矣。 [Classical Chinese, simp.]

From: The Book of Rites, c. 4^th – 2^nd century BCE

Nánfāng yuē mán, diāotí jiāozhǐ, yǒu bù huǒshí zhě yǐ. [Pinyin]

Those on the south were called Man. They tattooed their foreheads, and had their feet turned in towards each other. Some of them (also) ate their food without its being cooked.

Ferlus (2009) hypothesizes that the first syllable, 交 (OC *kreːw), originated from the etymon *k.raːw, whence also 獠 (lǎo, “general term for ethnic groups in southwestern China”).
