One of the Features of Cantonese —— Preserving Entering Tone
Cantonese is a southern dialect that retains more elements of medieval Chinese, and its most prominent feature is that it completely retains the common entering tones in medieval Chinese. Therefore, a large number of Tang poetry and Song poetry, if read in Cantonese now, can only meet the most basic "rhythmic beauty" of poetry.
