Language and culture are inextricably linked. When learning a foreign language, we often make mistakes when we don't understand the local customs, which not only causes displeasure to other people, but also puts us in an awkward situation without knowing the reason. Some local people may not take it seriously because the other people are foreigners and instead, they tell them the correct terminology and its taboos, etc. However, when some local people avoid telling the foreigners about the correct language and its taboos, the foreigners may be afraid to use the language again for fear of making mistakes. In order to avoid such similar situations, it is believed that if we can let students know such cultural taboos when teaching, many embarrassing situations can be avoided and students can learn more about the local culture and explore the influence of the culture and language. This paper provides a general understanding of the words and behaviors that are not allowed in certain places in Taiwan, and it will serve as a reference for Chinese language learners as well as for readers to understand the unique customs of Taiwan. Many Taiwanese language habits are influenced by Taiwanese dialect (Hokkien), and taboo words are no exception, therefore there are many words derived from Taiwanese dialect (Hokkien), and most of them are homophonic, puns, and associations. This paper attempts to include taboo words in the situation of hospitals, marriages, industries, and festivals in the hope of providing a broader analysis so that more people can understand the basic taboo language culture in Taiwan, and also learn the linguistic phenomena that influence the local culture through those taboo words. Furthermore, the study shows that we can have a general understanding of the psychology of a country's people from the taboo language culture.
