Until now from August, 1990, this author is keeping scholarly exchange both with scholars from the North Korea and China and with The Religious Division in China and The Association of Buddhism in China. Through the scholarly exchange, this author has collected many data and knowledges and, based on the experiences, attempts to describe the writing focusing on the subject $quot;The Direction of the North Evangelical Work in the Age of Unification$quot;. Therefore, prior to main description, this author makes clear that this writing focuses on China and the North Korea. Also, to support the main suggestions, it includes some contents excerpted from $quot;The direction and Work for the North Korea Evangelism$quot; in $quot;Won Buddhism$quot;, the 21st Edition in 1997, and $quot;The Religious Policy and Ways in China Evangelism$quot;, published in $quot;The Collection of General Won Buddhism Culture Treatises$quot;, and this author describes additional contents required in new parts of this article. Through the scholarly exchange with scholars from the North Korea and China as activities on this author`s own initiatives, it could be commonly shared that Wonbuddhism thought is to erect spiritual civilization and to use maternal civilization properly. This author believes that, through the more attention from religious society and the support for continuous studying, the more improved evangelical environments may contribute for the evolution of a unified thought among people. In this article, this author reviews the processes of exchange with the North Korea until now, and, based on the review, suggests 11 ways, which are available for the North Korea Evangelism, and 9 for China evangelical work. The conclusion of this article represents this author`s expectation that, because it is not a suitable time for direct evangelical work, some preparatory period is needed for it and, after that, religious workers should be officially sent in the proper time. This author had already sent 50 books of Scriture of Wonbuddhism with help from headquarters of Wonbuddhism and also graduate students who will perform the wide studies on Wonbuddhism thoughts in $quot;the Social Science Center in the North Korea$quot; are available. Therefore, given the situation, this author think that Wonbuddhism thoughts may take an important part of spiritual development and the activities for understanding Wonbuddhism thoughts will be more increased.
