Abstract：In order to explore the usage behavior and cause of emojis on social media, we analyzed the use of emojis in 1 800 958 microblogs under the topic of "Kunshan Case" on Sina Weibo. First, we analysis the frequency of emoji to study the phenomenon of repeated usage of emoji in the group, and then we classify popular emojis and micro-blog texts, we analyze the diversity of emoji usage of individual users. The result shows that: There are a lot of emojis in Weibo and the frequency of emojis is long-tailed and follow Zipf's Law; The evolution of popular emojis can reflect the public opinion of the event; Individual users are used to using 2~3 same emojis or different emojis with similar emotions. The emojis used by users are often related to the topics they express and are influenced by the psychology of herds, and the phenomenon of co-occurrence emojis is usually to strengthen the emotions expressed.
