The Chinese audiovisual textbooks "HOME WITH KIDS" contain a myriad of Chinese culture,yet existing studies have mainly focused on the "Cultural Points" section of the textbooks. Simultaneously,studies on the culture’s country-specific applicability remain uncommon.

Consequently,this paper elaborates the issue from the following dimensions.

(1) Taking the whole set of "HOME WITH KIDS"textbooks (three volumes) as the object of study,this paper recorded the quantity,category,location and presentation of cultural content distributed in each writing component,such as Texts,Grammar Points and Cultural Points,and summarized the organizational characteristics of the cultural content in this set of textbooks.

(2) Thoroughly analyzing the feedback of the questionnaire targeting students (HSK3-6)at the private middle school in Tollit,Mongolia,this paper investigated the suitability between the findings of cultural research of the textbooks and the school’s objectives regarding Chinese language curriculum.The results of the analysis showed that the textbooks "HOME WITH KIDS" can considerably satisfy various learning demands of the school's students(HSK3-6),and can effectively alleviate the lack of Chinese teaching materials in Mongolia.

(3) Through analyzing teacher interviews and observing instructional videos,this paper examined the actual implementation and feedback effects of the cultural content in the school’s intermediate and advanced Chinese lessons,so as to evaluate the merits and demerits of the selection of cultural contents in the textbooks "HOME WITH KIDS". On the one hand,the cultural content appear to be intriguing and positive. On the other hand,there are still some shortcomings in the selection and presentation of the cultural contents,such as misrepresentation,outdated narratives,incompletion and inappropriate illustrations.

(4) Based on the results of the survey and analysis mentioned above,this paper incorporated subject theory and teaching practice to explore the local adaptation of the cultural content in the textbooks "HOME WITH KIDS"from the perspective of "Single-Edition-Multi-Version" textbooks development,and provided suggestions for adaptation for Mongolian learners: 1) Tailoring the proportion and specific content of Chinese culture in the textbooks according to students’needs. 2) Reasonably selecting the cultural content that can be used for comparison between Mongolian and Chinese cultures. In this way,this paper seeks to provide a reference for the adaptation of the cultural contents of the textbooks"HOME WITH KIDS" for Mongolian Chinese learners and make a contribution to tackling the lack and inapplicability of Chinese textbooks in Mongolia.
