Zauzou (Rouruo 柔若, Jaojo, Raorou; autoynm: zau55 zou33) is a Loloish language of Tu'e District (兔峨地区), Lanping County, Yunnan, China. It is most closely related to Nusu.
In Tu'e District, Rouruo is spoken in Tu'e (兔峨), Bijifeng (碧鸡风), Wupijiang (吾批江), Guoli (果力), Xiaocun (小村), Jiangmo (江末), and a few other locations. The two major dialects are Guoli (果力) and Jiangmo (江末). Sun (2002) provides extensive vocabulary word lists for the Guoli (果力) and Jiangmo (江末) dialects.
Lama (2012) observes a sound change of *r- > Ø from Proto-Loloish as a Nusoish innovation.
