Cultural Image Translation Strategies from the Perspective of Eco-Translatology

The connection between language and culture determines that translation is not only the superficial transformation of language symbols, but also the deep transformation and transplantation of different cultures. Domestication and free translation of unique cultural images in the source language often fail to convey the unique cultural connotation of the source language, which will lead to the loss of the source language culture in the target language and greatly reduce the cultural value of translation. This paper studies cultural images in literary translation from the perspective of eco-translatology, and points out that cultural images not only have high literary aesthetic value, but also have rich cultural connotations, which play an important role in promoting literary communication and cultural dissemination. On this basis, this paper probes into the translation methods of translating cultural images, which are mainly foreignization and supplemented by domestication, and discusses the phenomenon of cultural loss when cultural images are trans-mitted in the process of literary translation.


Introduction
Cultural image is not an isolated language symbol. It has intertextuality in essence. According to the theory of intertextuality, the composition of any text is the absorption and transformation of other texts (Li & Zhu, 2016). This means that cultural image is also composed of the language symbols of cultural image and the dependent connection between its cultural signified, which is the result of the combination of language symbols and cultural meaning (Wei et al., 2019). After a long period of exploration and research in translation at all times and in all over the world, equivalence theory seems to have developed to a near perfect level (Chen, 2016). Many translators regard it as the guiding principle of translation. However, when dealing with the translation of cultural images, the consideration of the recipient's response is often contradictory to the goal of cultural transmission. On the basis of information theory, we should go beyond the rigidly bound comparison and entanglement of the two languages, emphasize the dynamic equivalence of information, and focus on the response of the target readers (Wang, 2011). Comparing the response of the target readers with that of the original readers, it includes not only the understanding of the information function of the two languages, but also the understanding and appreciation of the expression function, empathy function, aesthetic function and other functions (Zhang, 2017). Under the background of cultural globalization, the "cultural turn" of translation has become inevitable.
Because human beings form the same and similar association with some things in social practice, there is a certain degree of overlap between different cultures, and thus different degrees of equivalence relationship are formed in the process of translation (He, 2016). Image is a method often used in literary creation. The use of image, in essence, is to express abstract things with concrete things, enlighten unknown or difficult to know with known or easy to know (Wang, 2015). The intertextual nature of cultural image reveals the participation value of cultural image in a specific cultural discourse space, and reflects the relationship between cultural image and its language symbols, knowledge codes, cultural representation and other factors (Liao, 2011). The focus of contemporary translation theory research has shifted from comparative analysis of language structure and translation semantic equivalence to linguistic and cultural comparison and cultural translation strategies (Chai, 2001). Image refers to the specific image with a special meaning and literary significance in literary works. It is an amorphous and creative meaning, finding a fixed and expressive image, and a combination of abstract meaning and concrete image (Gu, 2011). This paper studies the cultural images in literary translation from the perspective of eco translatology, and points out that cultural images not only have high literary aesthetic value, but also have rich connotative cultural information, which play an important role in promoting literary exchange and cultural communication.

The Role and Dilemma of the Principle of Equivalent Effect in the Translation of Cultural Images
Since 1950s, many translation theorists at home and abroad have made detailed discussions on translation equivalence. For example, Cartford's "textual equivalence", Qian Zhongshu's "transformation", Fu Lei's "emphasizing resemblance but not resemblance", Xu Yuanchong's "seeking resemblance but not resemblance" and other translation theories all talk about equivalence in translation. Eugene Nida put forward the "equivalence theory" as a complete theory. Nida himself advocates that free translation is the first step in translation, and puts forward the famous dynamic equivalence theory: "The natural equivalence that is closest to the source language information is reproduced in the receiving lan-guage, first meaning equivalence, then stylistic equivalence" (Zhang, 2002). Translation is a tool of cultural communication, which is responsible for helping human beings to exchange thoughts and feelings, spread cultural knowledge and promote social civilization. Translation is not only a code-switching at the linguistic level, but also a cross-cultural transformation of spreading cultural information. Different languages have great differences in pronunciation, grammar and vocabulary, which bring insurmountable difficulties to translators. For example, Chinese belongs to Sino-Tibetan language structure, while English belongs to Indo-European language structure. It is difficult to realize the equivalent conversion between them at the language level. The purpose of communication is to enable two or all parties involved in communication to communicate and understand each other. In order for participants to communicate and understand each other, it is necessary to convey information clearly and accurately. Because different languages have different information bearing and expression forms, it is necessary to change the expression forms of the source language for translation. The equivalence principle is not limited to the surface structure of language, but seeks a higher level of dynamic equivalence, thus providing a new perspective and space for translators' work. Its philosophical foundation is the common core of human thinking, and people of all nationalities have similar life experiences and common language (Chen & Han, 2004). Due to the differences in natural geographical environment, humanistic environment and life thinking habits, different language groups and nationalities in different regions of the world have produced rich and different historical cultures. Each language not only reflects the concept of the objective world and the common experience of mankind, but also carries its own unique history and culture, cognitive thinking mode and belief. To some extent, the transformation of language symbols is only the surface of translation, while the essence of translation lies in the dissemination of cultural information. Therefore, in order to convey the cultural images in the source language profoundly and properly to the target readers, translators must understand the characteristics and differences between English and Chinese cultures. Table 1 shows the statistical data of the introduced book types.
Because the languages and thinking of different nationalities are strikingly similar in some aspects, cultural images, as a unique generalization and expression of a certain language, sometimes have the same similar connotations and associations in another cultural tradition. There is no difficulty in guiding this kind of translation with the principle of equal effect. If translation only conveys semantics approximately and loses cultural connotation, semantic communication is incomplete, unfaithful and fails to achieve translation goals. Domesticating the cultural concepts in the source language text into the target language culture in translation is an effort to give up the original and go to the end. The purpose of translation is to promote cultural communication, not to realize cultural unification. Introducing rich culture from the source language into the target language will greatly enrich and develop the target language, and make its cultural connotation and language expression art more colorful. In the process There can be several translations of the same source text, which can be consi-

Cultural Image and Its Translation
Foreignization and domestication are two interrelated translation strategies, which can be regarded as an extension of the traditional concepts of literal translation and free translation, but these two concepts are not completely equivalent. Literal translation and free translation mainly focus on how to deal with form and meaning at the linguistic level, while foreignization and domestication expand their horizons to the linguistic, cultural and aesthetic levels, thus breaking through the limitations of linguistic factors. Language is the carrier, product and important component of culture, so we can say that language and culture are closely related. Different nationalities breed different cultures, and there are different differences between different cultures. The core idea of foreignization and domestication is the value orientation based on the cultural context, rather than sticking to the value orientation at the language level. Generally speaking, foreignization requires the translator to approach the author and reproduce the content of the original text in a way that the readers of the source language are accustomed to. When the images in the source language can produce consistent or similar effects in the target language, that is, the readers' reactions are the same, literal translation can be adopted to retain the cultural images. For example, both English and Chinese have a large number of phrases with animals as images, which are vivid and intuitive, and easy to produce direct image effects, and then associate with the cultural connotations they carry. Based on the important position of cultural images in literary translation, translators should carefully study the aesthetic value of cultural images and the connotative cultural information they carry, carefully analyze readers' cultural horizons and receptivity, comprehensively consider various factors and carefully choose translation strategies. Translation of cultural images should not only consider language differences, but also pay close attention to cultural differences. How to deal with cultural differences is often the key to the success or failure of translation. There are many words with rich cultural characteristics in both English and Chinese. In translating such words, we should adhere to a general principle: on the one hand, we should convey the cultural characteristics of the source language as much as possible; on the other hand, we should not exceed the target language culture and the acceptability of the target language readers. When the cultural connotations of the images in the source language cannot be accurately expressed in the target language, they can be replaced by images that conform to the expression habits of the target language and are familiar to the target readers. In this way, although the image of the source language is discarded, the corresponding image in the target language can still be used to make the target readers have similar or similar reactions to the source language readers and obtain roughly the same artistic feelings. With the development of translation and cross-cultural communication, many foreign cultural images have been accepted by Chinese readers. When translating such cultural images, it is unnecessary to explain, process or replace them with Chinese cultural images. The composition of communicative competence is shown in Figure 2.
Alienation translation is faithful to the original text and the original author, which is conducive to maintaining the artistic image of the original text, enriching the language and culture of the target language, embodying cultural equality and promoting cultural exchange. However, excessive alienation will make the language of the translated text unsmooth, thus affecting readers' understanding of the translated text. Generally speaking, the expressions with foreign cultural characteristics are often figurative languages, and preserving the figurative languages in the original text is equivalent to reserving opportunities for Chinese readers to understand western culture. At the same time, the continuous introduction of fresh images is also conducive to improving the interpretation and digestion ability of Chinese culture to foreign cultures. Behind the contradiction between literal translation and free translation lies the contradiction between domestication and foreignization in essence (Lu & Rao, 2015). Traditional translation theory generally emphasizes content over form, and often uses the cultural images of one's own nation to copy the cultural images of other nations, so that the target readers can get the same strong feelings as the original readers. Any language has "alienation tolerance", and readers will have a kind of expectation for different cultures when reading works translated from foreign languages. The translation model based on big data can be expressed in pyramid form according to the depth of language break-up, as shown in Figure 3.  The key to the intertextuality of cultural images is to use the semantics of images to arouse readers' imagination, so that they can feel the exotic atmosphere of cultural images in the source language. In the translation of cultural images, the translator has to abandon the literal meaning of the original text when he is limited by the social and cultural differences of the target language, in order to achieve a free translation method which is consistent with the content of the original text and has similar main language functions. Because cultural images are often the crystallization of a nation's wisdom rather than the works of a writer or author, this contradiction is more reflected in the translation of cultural images as the target language or the target language. Although this difference does not affect the translator's understanding of the basic semantics of intertextual texts, it is difficult to reproduce the original meaning of cultural images, that is, to completely reproduce the intertextuality of cultural images in the same form, because the parent structure on which cultural images depend has changed, and the cultural images reconstructed by translators are only a possible approximate reproduction.

Conclusion
Culture is diversified, and the diversity of culture makes all ethnic groups have many vivid cultural images. However, due to the differences in natural environment, social system, religious belief, customs, ways of thinking, etc., there are also great differences in the expression of languages bearing culture. Alienated literal translation of cultural translation should avoid the simple understanding of literal translation as "qualitative translation", and avoid the problem that translation is not up to standard, because the target language is too "qualitative".
Whether the image is properly handled directly affects the success of translation.
Grasping cultural images can deepen the translator's understanding of intertextuality and improve his translation strategies. This intertextual relationship is manipulated by the translator, whether it is delivered directly or rewritten in a meaningful way, which can't get rid of the translator's grasp of the social and cultural intertextuality outside the text. On the basis of being familiar with the source culture and the target culture, translators must translate with a high sense of responsibility and coordinate the relationship between the principle of equal effect and the transmission of cultural factors, so as to seek the best combination of the two. Interpreting cultural images in translation from the perspective of intertextuality will inevitably bring new inspiration to translation studies, which can not only help scholars better understand translation activities, but also improve translators' ability to deal with text and extra-text factors in translation.
