"Danxi Theory" had deep influence on the traditional medicine in Korea and Japan. In Korea, the compilation of Yi Fang Lei Ju and Dong Yi Bao Jian referred to the medical works of ZHU Danxi and that of his students, the Korean doctors advocated the theory of ZHU Danxi' s theory of " four injuries by qi, blood, phlegm and stagnation", and quoted large number of formulas and herbs from Dangxi' s works into the above books. In Japan, Tashiro Sanki ( 田代三喜)had came to China and studied medicine from Japanese monk Yue Hu, who was the disciple of YU Tianmin (a private disciple of ZHU Danxi). After returned to Japan he energetically initiated Danxi' s theory and classified diseases to blood disease, qi disease and phlegm disease (water toxin) according to Danxi' s theory of "four injuries by qi, blood, phlegm and stagnation". His student Manase Dosan (曲直濑道三) set up a "Danxi Society" and spread Danxi Theory in Japan and therefore the unique medical system "Gose Ha shcool 后世学派" was formed. His student Manase Censaku (曲直濑玄朔), and Manase Gensaku' s students Okamoto Cenya(冈本玄治), Nagasawa Doju(长泽道寿 )and Hurubayashi Kengi(古林见宜) spread and developed Danxi Theory, which was popular in Japan for more than 200 years. It was proved that Danxi Theory had deep and far influence on the formation and development of overseas traditional medicine in Korea and Japan.
