In this era of rapid development, the needs of the audience are becoming more and more rich and diverse, and the traditional pattern of publishing content production practices has been slowly broken, and it has also changed from the traditional "solid" to "liquid". Based on the perspective of "liquid theory", this paper mainly discusses the publishing needs and publishing practice status of the audience, and also dialectically discusses the freedom and restraint of content management power brought by the "information cocoon" to the audience, and analyzes the trend of "liquefaction" of publishing content production practice and the concept, principle and working routine of "liquid" content production.
