This paper examines the rapid evolution of net slang and its consequential impact on Standard Mandarin, highlighting the interplay between net slang and traditional linguistic norms. The study begins by delineating three principal characteristics of net slang: multiformity, simplicity, and flexibility. Through a survey assessing Chinese attitudes towards net slang, both positive and negative viewpoints are revealed. Results indicate that while net slang can enhance communication with creative elements such as emoticons, it also risks grammatical divergence and semantic deviations. These impacts are particularly pronounced in the realm of Chinese language education, where net slang affects graphology and fosters misinterpretations. Despite these challenges, the paper advocates for a balanced approach, proposing the integration of beneficial aspects of net slang into Standard Mandarin following rigorous evaluation. Emphasizing language sustainability, the study underscores the role of educators and parents in promoting reading, thereby ensuring the harmonious coexistence of net slang and standard language while preserving linguistic integrity for future generations.
