Globally, China's status continues to rise, and learning Chinese has become an increasingly popular choice for foreigners. However, mastering Chinese phonetics poses is the greatest challenge for learners. This study investigates the deviations and their causes in the Chinese phonetic learning of foreign students. The research found that interference from the native language, linguistic thinking habits, and incorrect learning methods are the main causes of deviations. At the same time, teacher guidance errors and textbook issues also impact students' phonetic learning. To improve the Chinese phonetic learning of foreign students, teachers should guide students in correctly understanding and mastering Chinese tones, syllable combinations, and pronunciation positions through demonstrations and exercises. Moreover, updating teaching materials, enhancing teachers' professional levels, and teaching according to students' characteristics are crucial to improving Chinese phonetic teaching. This study has significant implications for increasing the accuracy and effectiveness of Chinese phonetic learning for foreign students.
