I choose the article in Daily Character from 1st, January to 31st, May in 2018. And then, I classify articles to three aspects, including character, news and special topic. The articles about character mainly focus on people. And those articles about news mainly discuss some hot events. The last aspect is special topic. In different aspects, these articles have more detailed classification. In classification of character, the articles are divided into two parts. The first part only reports one person, and the second part’s interviewees are over one person. And the articles in news are divided into society, entertainment and daily life. The special topic includes summarized articles，commemorative articles and activity/ marketing articles.
