The Chinese Bush-Warbler is a plain brown bird that breeds from southern Siberia to southern China. It keeps hidden in vegetation on its breeding grounds, and its winter range is uncertain.
The upperparts are plain olive-brown and the underparts pale. Pale tips on the undertail coverts are narrow and often poorly defined, and the head pattern is plain.
It is highly skulking on its breeding grounds. Its call resembles that of the Brown Bush-Warbler but is slightly higher and thinner.
