When can Wu-speaking areas have such a strong mother tongue atmosphere as Cantonese areas? Why?

impossible. Cantonese and Wu dialect are completely incomparable. On the Disintegration of "Mandarin-Gossip" System. In ancient society, due to the imperial power, the country formed two spatial dimensions: temple-countryside, which was maintained by the gentry class in the middle, thus forming three languages. Temple bureaucrats speak and write mandarin in official business, and convey written decrees; Rural people can't read, and they talk in vain and read gossip in their lives; For local literate gentry, they accept written decrees, and they can directly convey gossip to rural farmers. This can be described as the classical official-gentry-people ternary system of "Mandarin-gossip". In this ternary system, the functions of Mandarin and gossip are independent of each other, so they are usually inconsistent or far apart. Forty-nine years later, the traditional society died completely, the gentry class disappeared, the central government unified the whole country and went deep into the grassroots, the literacy rate rose rapidly, and new media such as newspapers and radio went deep into every corner as the carrier of government orders. This leads to two situations. One is that rural people can listen and speak Mandarin more quickly through broadcasting, and the other is that they can read the corresponding characters in Mandarin. In fact, this leads to the unnecessary reading of gossip, and the gossip returns to the function of reading gossip for nothing, that is, daily private life. At this time, a modern country with "Mandarin-Gossip" and a dual system of individuals are formed. Seventy-six years later, the household registration system was liberalized, and the population movement was strengthened, which led to another impact on the function of gossip. In daily private life, local gossip could not be used all the time, and only Mandarin (Mandarin) understood by both locals and foreigners could be used. At this time, Mandarin has begun to replace the function of gossip, especially in areas with developed economy and large foreign population. After the new century, with the rise of internet technology, the network has become the biggest new media after newspapers, radio and television. Unlike the former, the network can not only convey state decrees, but also be a unified platform for people's daily communication. Because the network information is conveyed by words, and the gossip of reading has long been lost, the pronunciation of words feeding back to people's minds can only be Mandarin. At this point, Mandarin further replaces the function of gossip. At this time, it forms a nearly unitary system that tends to be single mandarin. It can be seen that the only trend of gossip in the current era is to be replaced by mandarin. Therefore, the best way to protect gossip can only be to make it have all the functions of Mandarin, that is, to realize the unitary system of "officialdom of gossip". This requires that gossip must have an independent political identity and a perfect orthographic system. But on the mainland, this new monistic system is bound to collide with the old monistic system of Mandarin. The attempt to protect gossip by calling for dialect learning and making dialect TV broadcast programs is essentially to return today's nearly unitary system to a dual system, but this is impossible to achieve. The ultimate fate of gossip is extinction, and only Mandarin can survive.
