Network language has two meanings: first, it refers to terms and vocabulary related to Internet and computer technology and application; The second is the language people use to communicate and express themselves through computer and Internet media.

Network language is a new language form which is different from traditional print media with the development of network. With its concise and vivid form, it has been favored by the majority of netizens since its birth and developed rapidly.

Network languages include pinyin or English abbreviations. Numbers with certain meanings, vivid network animations and pictures are mainly used by internet addicts at first to improve the efficiency of online chat or some needs, and over time they have formed a specific language. The emergence of network neologisms mainly depends on its own vitality. If those vibrant online languages can stand the test of time, we can accept them after the convention is established. And if you can't stand the test of time, you will soon be abandoned by netizens.
