Tones
The Qiyang dialect is quite unusual in that it is reported to have two "double contour" tones, high and low fall–rise–fall, or perhaps high fall – low fall and low fall – high fall: the entering tones ''yin qu'' (阴去) (4232) and ''yang qu'' (阳去) (2142). However, phonetically the pitch of a syllable depends on the voicing of the initial consonant, so these are phonemically a single tone. Moreover, the final fall of the ''yin qu'' tone is "not perceptually relevant", so it may be that 'dipping' (for ''yin qu'') and 'peaking' (for ''yang qu'') are a sufficient categorization.References
