Abstract
There has been a tremendous rise in the growth of Chinese Microblog--- Sina Weibo in the past few years. Sina Weibo contains many interesting hot issues. In particular, the trend of some hot topics can be described by the soliton wave model based on some hypothesis and parameter settings. The theoretical strategies to control the trend of hot topics are stated by employing the lump soliton solution theory of the KdV equation and KP equation.
