　　Chapter One Introduction 
　　Nowadays， it is very popular for Chinese young people to “晒xx” on the internet. You can “晒” almost anything on the internet such as your salary， pictures， secrets， tastes etc. On the internet，， everyone could become a sharer （晒客）. From those popular internet slogans like “今天你晒了吗？” . we can see how powerful the character “晒” is in Chinese word-building. 
　　However， where does this network term “晒” come from？ To get an answer for this question， we are going to make an analysis of the popular hypotheses about the source of the term and explain it in the perspective of cognitive linguistics.

　　Chapter Two The Meaning and The Source of The Network Term “晒” 
　　2.1 Where does the network term “晒” come from？ 
　　With all the definitions given below， we still cannot give a good explanation to the network term “晒”. After a thorough research， I found out that in all those different hypothesis about the source of the network term “晒”，only three of them are persuasive. 
　　2.2.1 The network term “晒” is the transliterated word of “share”. 
　　Nearly 85% of the people support this hypothesis by publishing their opinions through all kinds of media. They call people who share things on the internet “晒客 （sharer）”. 
　　2.2.2 The network term “晒” is loaned from the Cantonese slang “晒命”. 
　　In Cantonese， “晒命” means to constantly or eagerly show off what one is proud of. Therefore “晒” means “炫耀 （to show off）”， which is a little bit negative. Nevertheless， it becomes more and more neutral with the meaning showing things on the internet. Some people believe that this is the origin of the network term “晒”. 
　　Chapter Three The Cognitive Explanation of The Network Term “晒” 
　　As we’ve mentioned above， we believe that the network term “晒” originates from the transliterated word of the English word “share”. Therefore， in this chapter， by digging up the connotation of the word “share”， we hope that we can get a better understanding of the network term “晒”.
