The purpose of this paper is to analyze the reasons why “expert advice” triggers publicresistance, so as to better alleviate the relationship between social subjects and promote the healthydevelopment of modern democratic society. We used Python to capture the posts of six related topics inSina Weibo, and firstly, we used ROST CM6 to analyze the word frequency of 830 posts, and then twocoders summarized the word frequency results in order to find out the four social issues involved in theexpert’s suggestion. Subsequently, the text content of the 830 posts was clustered using topic analysis ofLDA to produce five thematic results. The word frequency analysis and manual summarization resultsshowed that most of the suggestions from experts were related to the four topics of work and wages,childbirth, home purchase and marriage, and the LDA thematic clustering yielded a total of five themes,which showed that the detachment from reality, ineffectiveness, and one-sidedness of the experts’suggestions, as well as the profit-seeking nature of the media reports and the opacity of the informationsources, were the main reasons for the public’s resistance.
