Learning Chinese as a foreign language demands not only mastering the written characters but also acquiring a deep understanding of its unique phonetic features. Among these, three critical phenomena—erhua (retroflex suffixation), the neutral tone, and tone sandhi—play a pivotal role in the accuracy of pronunciation and fluency of verbal expression. These phonological characteristics are fundamental for effective spoken communication and provide insight into the cultural and social nuances inherent in the Chinese language. Understanding and correctly applying these features can significantly enhance comprehension and interaction in various communicative contexts. Furthermore, these phonetic phenomena embody rich linguistic traditions that reflect regional dialectical variations and historical language development. Moreover, in the field of Chinese language education, it is imperative to develop instructional strategies that balance theoretical knowledge with practical application. Effective pedagogy should aim not only at transmitting linguistic concepts but also at developing students' auditory discrimination, pronunciation skills, and a professional attitude towards language use. This article explores these three phonetic phenomena from both linguistic and educational perspectives, reviewing relevant research and identifying challenges faced by learners. Based on this examination, a comprehensive teaching method is proposed that integrates theoretical understanding with hands-on practice through interactive activities and real-life language use scenarios. This approach seeks to facilitate a holistic learning experience, ultimately supporting the comprehensive development of students as proficient and confident speakers of Chinese, well-prepared for professional and intercultural communication.
