Literature Review This chapter consists of three sections. Section 2.1 gives brief explanation of the translation of public signs. Section 2.2 provides the theoretical basis. Section 2.3 introduces the evaluation of the existing empirical studies on the translation of public signs. 2.1 Brief explanation of the translation of public signs in scenic spots Public signs in scenic spots refer to road signs, signboards, slogans, warning signs, brief introduction of scenic spots and names of scenic spots, etc,which are published in the scenic spots for public notice, hint and warning. Theoretically speaking, the translation of public signs should be faithful to the cultural connotation of the original text. Therefore, the translation of public signs in tourist scenic spots should not only enable foreign tourists to understand signs or brief introduction in the scenic spots, but more importantly, to convey the unique culture through language in a more attractive way. Secondly, cultural communication is carried by language. Therefore, the translation of public signs should not only be accurate in terms of words, but also make the translated text have a literary beauty and give foreign tourists a lot of imagination, so as to enjoy more and greater pleasure in the tour. However, it is not clear whether the translation of public signs in practice can meet these criteria at the same time. Local culture is the memory left by the common life of one or more ethnic groups. Through the crystallization of the habits and thinking mode of the ethnic group, the culture reinterpreted is unique, ethnic and pure. As foreign tourists grow up in an environment with different languages and cultures, it is difficult to find the translation of language equivalence and cultural meaning in a language or culture. Therefore, it is not easy to achieve accurate standards in practice. This research aims to deal with English translation of public signs for foreign tourists, which include the guide signs, instructions, attractions guide, introduction and so on. Due to poor foreign language proficiency of translators, lack of sufficient cross-cultural awareness or poor foreign language proficiency of personnel in the licensing unit, from the translation to the finished products of the brand may lack the spirit of excellence, or in addition to some relatively easy to find out the low-level mistakes, many failures are identified due to cultural differences. Incorrect transfer of mother tongue leads to Chinglish and pragmatic failures. For example, basic language errors include: spelling, vocabulary errors, collocation errors; Language failure, inconsistent translation criteria, and all these problem are identified and need to be corrected. 2.2 The Eco-translatology Theory The concept of eco-translatology was proposed by Hu gengshen, a Chinese scholar. "It's a kind of an ecological approach to translation", or "Translation studies from an ecological perspective. (Hu gengshen, 2008:13) Scholars who hold the view of ecological translation will define translation as "The translator adapts to the selection activity of the ecological environment". The ecological environment is not only the language environment, but also the world of the original text and the world faced by the translator in culture, communication, society and other aspects. It can be seen that ecolinguistic translation studies put translation activities in a broader perspective, not just limited to the perspective of linguistic equivalence. From another emphasis on the translator's adaptation and selection, it can be seen that eco-translatology emphasizes the translator as the center status. Eco-translatology is a new approach to the essence and process of translation, which also provides a new translation method, as well as translation principles and translation criteria for the translator. When the translator translates, it is necessary to start from "three dimensions" (language dimension, communication dimension and culture dimension) to make translation text can achieve the degree of multi - dimensional transformation. 2.3 Related studies 2.3.1 Studies on translation of public signs As is known to all, public signs performing functions of directing, prompting, restricting, and compelling, play a significant role in guiding foreigners to live and tour in China more comfortably and conveniently. Many scholars have engaged in this field and conducted various researches on the public signs translation. The English translation of the public signs has already been researched from different perspectives. Some scholars focus such information about the public sign as the definition, the functions, the characteristics, the language style and some problems or errors in the current English translation of the public signs and then put forward some principles, strategies or procedures on the English translation of the public signs in practice(Wang Bi, 2017). J. Thomas put forward the concept of pragmatic failure in the context of Cross-Cultural Pragmatic Failure in 1983. Pragmatic failure refers to the people of different cultural background in language communication because of the different speech patterns or expression habit, to have some misunderstandings or obstacles in the cross-cultural communication so that influence the effect of communication(Thomas J, 1983). Shu hui juan believed that the original text is relatively fixed, no matter whether it can be correctly interpreted or whether the words in the translation are wonderful or not, it is up to people. Therefore, from the perspective of ecological translation, the process of translation should be an alternating cycle of translator's adaptation and selection(Shu hui juan, 2010). In conclusion, previous studies on the translation of public signs in scenic spots have played an important role in regulating the quality of public signs. Through these studies of the principles and methods of the applicable public signs, there are many things that can be borrowed from these papers, so as to deepen the study of public signs. 2.3.2 Studies on translation of public signs from the perspective of Eco-translatology Recent years, some studies have been conducted to discuss the translation of public signs from the perspective of the Eco-translatology Theory. Many scholars believe that the ecological environment of translation is generally a "world" represented by the original text, the target language and the source language（Hu Geng shen, 2008). Xiao le(2014) considered that Chinese public signs are characterized by directness, brevity and conciseness, and most public signs are completed by imperative sentences. Western culture often attaches importance to rational analysis and form perfection. For this reason, English public signs are characterized by preciseness, specificity and accuracy, which pay more attention to objective thinking and occasionally use euphemistic imperative sentences. Therefore, in many cases, English public signs are mostly characterized by humanization and humanistic care. And in order to translate public signs well, we must understand the language style of English public signs, which must be clear at a glance and express its meaning clearly in the limited space. English public signs usually use capital letters to attract the attention of readers and the language should be formal. Moreover, westerners like to go straight to the subject, so translators of public signs should enhance the awareness of the target audience, and pay attention to the fact that the English translation should conform to the thinking mode, language expression habits and characteristics of English public signs of the target audience (Wang qin Zuo wei, 2012). Through previous studies, many researchers have laid a theoretical foundation for the study of public signs in scenic spots. From the three dimensions of language, culture and communication, the linguistic characteristics of public signs and the transformation of cultural thinking mode are clearly elaborated. What#8217;s more, examples are illustrated in these papers to point out the direction for future studies. On the basis of the previous paper, this paper will further analyze how to integrate the local conditions and customs of Nanjing on the premise of correct and beautiful use of public signs, so that more foreign tourists can not only have a more comfortable experience when visiting this scene, but also experience the unique local conditions and customs, cultural habits and hospitality of Nanjing, highlighting the local and national characteristics. So this research will make a deep analysis on translation of public signs and hope to bring some recommendations or suggestions to improve the application of translation of public signs .
