What does Wu Nong's soft language mean?

Suzhou dialect has always been called "soft language of Wu Nong", and its biggest feature is "soft", especially for girls. Wuxi dialect, Jiaxing dialect, Shaoxing dialect, Ningbo dialect and other dialects belonging to the Wu dialect family are not as soft as Suzhou dialect. Whether a dialect is good or not is a bit like listening to foreign songs. In fact, it does not depend on whether it is easy to understand, but mainly depends on intonation, speed, rhythm, pronunciation and vocabulary. Wu dialect and Xiang dialect (referring to old Xiang dialect) are the earliest dialects among the seven major dialect families in Chinese, so Wu dialect has preserved quite a lot of ancient sounds so far. A major feature of Wu dialect is that it retains the full voiced initial, has seven tones, and retains the entering tone. Auditively, if a dialect is spoken too fast and cadence is too strong, we often call it "too hard", such as Ningbo dialect; But if the speech speed is too slow and there is no obvious cadence, we often call this kind of speech "too awkward", such as Henan Live. Suzhou dialect has a peaceful tone without cadence, and its speech speed is moderate without cadence. Pronunciation, it feels closer to the front, a bit like singing in a low voice.
