Culture and translation are closely linked. Tourism itself demonstrates broad cultural communication in that sense. Therefore, in order to facilitate communication between different cultures, the translator must handle the cultural elements in the tourism materials accordingly. Among these cultural features of tourism materials, the cultural lacuna is one of the most obvious characteristics that occupy a large part in the translation of tourism materials. The cultural lacuna refers to either linguistic facts or cultural facts that appear in one culture, people, however, cannot find equivalence or correspondence in another culture. The reasons for the cultural lacuna are often due to the peculiarity or diversity of different cultures. The author of this dissertation tries to find ways to solve this phenomenon in tourism materials on the theoretical basis of domestication and forenization. Regarding the cultural lacuna in tourist materials, it is suggested that the interpreter should consider and study these two strategies dialectically and historically, rather than statically and absolutely. In accordance with the above principle, specific approaches to solving the problem of cultural lacunas in tourist materials are proposed.
