In the period of rapid economic growth of Taiwan, starting in the 1960s and proceeding through the 1980s and 1990s, Yiguandao spread its influence by entering business and industrial development. Many members became important businessmen, for instance Chang Yung-fa, the founder of the Evergreen Marine Corporation, was the chief initiator of a Yiguandao subdivision and in the 1990s almost all the managers of his corporation were Yiguandao members. The same strategy of "combining missionary work and business" facilitates the development of Yiguandao in mainland China, where Yiguandao businessmen began reestablishing the religion since the 1980s by means of investment. Another mean by which Yiguandao expanded in Taiwan was that of charity. Through the years of the ban Yiguandao persisted as an underground phenomenon. In 1963 it was reported that the religion had about fifty thousand members, and grew rapidly through the 1970s and the 1980s, counting more than 324,000 members in 1984. Five years later in 1989 Yiguandao had 443,000 members or 2.2% of Taiwan's population. Recognizing the social power of the religion, the Kuomintang officially gave Yiguandao legal status on 13 January 1987. As of 2005 Yiguandao has 810,000 members in Taiwan (3.5% of the population) and tens of thousands of worship halls. Its members operate many of Taiwan's vegetarian restaurants. Korea Yiguandao was transmitted in the Korean peninsula (Hanja: 일관도 Ilgwando) in the 1940s through the pioneering work of Dukbuk Lee, Sujeun Jang, Buckdang Kim and Eunsun Kim. Korean Ilgwando is incorporated as the International Moral Association which was founded in the 1960s by Buckdang Kim (1914-1991), and as of 2015 it has 1.3 million members in South Korea (2.5% of the population). Japan In the 1950s Yiguandao spread to Japan (where its name is Ikkandō), during the persecutions in mainland China, and there it has attracted about fifty thousand members from both Chinese minorities and Japanese ethnic groups. It is articulated into two main branches: ① Kōmōseidōin (孔孟聖道院 Kǒng Mèng Shèngdào Yuàn, "School of the Holy Way of Confucius and Mencius") and Sentendaidōnihonsoōtendan (先天大道日本総天壇 Xiāntiāndàdào Rìběn Zǒng Tiāntán, "Japan Headquarters of the Great Way of Former Heaven") with 8000 members each; and ② Tendō (天道 Tiāndào, "Heavenly Way") and Tendo Sotendan (天道総天壇 Tiāndào Zǒng Tiāntán, "Headquarters of the Heavenly Way") respectively with 300 and 30,000 members.
