in promoting human rights and the use of the spoken and written Taiwanese (see Pe̍h-ōe-jī), both during Japanese rule, as well as the martial law period of the Republic of China, during which the exclusive use of Mandarin was legally mandated. As such, the church has been associated with the Taiwan Name Rectification Campaign and the pan-green coalition. Several Taiwanese religious organizations have extended their operations beyond the country. Several organizations, especially Buddha's Light International Association (Fo Guang Shan), Tzu Chi Foundation, Dharma Drum Mountain and Chung Tai Shan, have set up branch temples (or centres) and extended their humanitarian or missionary works around the world. Buddhist-Taoist religious belief makes up 93%, Christian 4.5%, and others 2.5%. Food Pearl milk tea (also known as bubble tea or boba) is a popular tea drink available in many parts of the world. A notable Japanese influence exists due to the period when Taiwan was under Japanese rule. Taiwanese cuisine itself is often associated with influences from mid to southern provinces of China, most notably from the province of Hokkien , but influences from all of China can easily be found due to the large number of Chinese who immigrated to Taiwan at end of the Chinese Civil War and when Taiwan was under Chinese rule (ROC). In the process, Taiwan developed a distinct style of cuisine. Languages The language with the most native speakers in Taiwan is Taiwanese Hokkien, or "Taiwanese" for short, spoken by about 70% of the population. People who emigrated from mainland China after 1949 (about 13% of the population) mostly speak Mandarin Chinese. The Hakka, who make about 13% of the population, speak the distinct Hakka language. The Formosan languages are the ethnic languages of the Taiwanese Aborigines, comprising about 2.3% of the island's population. Standard Chinese is the official language and is almost universally spoken and understood. English is taught universally, starting in elementary school. Taiwanese Mandarin, derived from Standard Chinese, is spoken at different levels according to the social class and situation of the speakers. Some terms have different meanings in Taiwan and mainland China, such as: 土豆 (tǔdòu), which means peanut in Taiwan, but potato in China. There also exist differences in official pronunciations of a few words such as 垃圾, which is pronounced lèsè in Taiwan but lājī in China, with the former being derived from Shanghainese.
