First of all, it should be pointed out that there are many theoretical deficiencies in the analysis and definition of the phenomenon of private writing at present, and the most important one is the confusion of theoretical standards. For example, some people call private writing new state literature (the new state itself lacks a clear theoretical definition, so-called describing a new current state), while others say that private writing is a natural extension of the novelist's life, and the novel characters, narrative characters and the novelist himself are integrated in a free state. The key issue here is that the definition of privatization must be compared with the definition of publicity. Private refers not only to the way of experience or writing, but also to the type of experience or writing content. The core of privatization lies in its strict opposition and difference with the public and groups, not in others (just like the opposition and difference between the private sphere and the public sphere). In this way, private writing can be distinguished from specious things such as the so-called new state or the writer's current emotional state, and it can also be distinguished from concepts such as artistic style and artistic personality. The writer's current emotional state is not necessarily a personal emotional state; Similarly, the new state is not necessarily a personal mood or experience state. They may all be public, group and socialized at the same time. For example, if the new country refers to a fairly common (and therefore very public) social and cultural state in Chinese mainland in the 1990s, such as marketization, secularization and globalization. Then the performance and recognition of this state is precisely the loss of privacy rather than the gain of privacy. Similarly, if some writers' works, which are considered private, show complete recognition of the current business discourse, then this recognition reflects the loss of privatization (because the current business discourse is undoubtedly a powerful discourse with universality and publicity).
