The paper does some research on the importance and nature of culture in teaching based on the relationship between language and culture of teaching of Chinese as a foreign language. Foreigners can＇t learn Chinese without its culture and language teaching can＇t go without culture teaching either. Language teaching and culture teaching are two different ones with their own features but can＇t be replaced. In the teaching of Chinese as a foreign language, cultural background teaching should be done in both language and practice teaching. Various and flexible teaching ways are aimed for different students to promote culture communication and combination.
