Nong is a transliteration of the word "ren" in the ancient Wu language, which describes the clear and elegant pronunciation of Wu speakers. There is a poem in Li Bai's "Hengjiang Ci" called "People are good at crossing the river and farming inherent vice", which is equivalent to "People are good at crossing the river and people are evil at crossing the river".
In today's Shanghai, Ningbo and other places, Nong stands for "You", while in other places it is "Nai", "Er" and "You". In modern Wu dialect, the pronunciation of the word "Ren" in northern Wu dialect is no longer pronounced as "Nong", while the word "Ren" in southern Zhejiang retains the ancient eastern accent of "Nong".

Wunong soft language is generally used to describe Suzhou dialect vocabulary in Wu language. Suzhou dialect belongs to Su Hu Jia, a small piece of Wu dialect in Taihu Lake. Su's Wu accent is elegant and euphemistic in Wu dialect area, which is called "Wu Nong Soft Language". Wunong soft language usually refers to Suzhou dialect, and is sometimes used to describe Shanghai dialect. Wu dialect in Ningbo and other places is relatively hard, so it is generally not described as "soft language of Wu Nong".
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 family are not as soft as Suzhou dialect.
Whether a dialect is good or not depends mainly on intonation, speech 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.
