Laurent Sagart
As noted by Laurent Sagart (2011) and others, Waxiang appears to share some words with the Caijia language of western Guizhou. Sagart (2011) considers Caijia to be a sister of Waxiang. Currently, Waxiang is classified as a divergent Chinese variety rather than a non-Sinitic language. Similarities among Old Chinese, Waxiang, Caijia, and Bai have also been pointed out by Wu &amp; Shen (2010).
