The phenomenon of language fossilization is prevalent in the process of second language acquisition. Based on an examination of the concept, classification, and theoretical explanations of fossilization, this paper focuses on second-year students from the Mass International High School in Chonburi, Thailand. It describes the specific manifestations of fossilization from four dimensions: phonetics, grammar, vocabulary, and pragmatics, and analyzes the underlying causes, covering four aspects: language transfer, cognitive factors, affective factors, and teaching environmental factors. On this basis, this paper proposes targeted systematic teaching strategies, encompassing four aspects: phonetic teaching, grammatical teaching, affective factors, teaching strategies, and interaction. The study suggests that scientific identification and comprehensive intervention can help break through learners' bottlenecks in Chinese language learning, providing theoretical and practical references for Chinese language teaching in Thailand.
