As a Chinese person, I have a natural advantage as Mandarin is my mother tongue, allowing me to express the meaning and sense of Mandarin more accurately in pronunciation, grammar, and vocabulary. I have a deep understanding and grasp of the cultural connotations of Mandarin due to my cultural background. These cultural connotations include idioms, proverbs, allusions, etc., which are important content for learning Mandarin. When communicating with students during the teaching process, I can better understand the language habits and expression styles of my students, facilitating effective communication and improving the teaching effect.
