what's the meaning of yin and yang
Yin and yang In Chinese philosophy, yin yang (/ˈjɪn ˈjɑːŋ/; Chinese: 陰陽 yīnyáng, lit. "dark-bright", "negative-positive") describes how seemingly opposite or contrary forces may actually be complementary, interconnected, and interdependent in the natural world, and how they may give rise to each other as they interrelate to one another. Many tangible dualities (such as light and dark, fire and water, expanding and contracting) are thought of as physical manifestations of the duality symbolized by yin and yang. This duality lies at the origins of many branches of classical Chinese science and philosophy, as well as being a primary guideline of traditional Chinese medicine,[1] and a central principle of different forms of Chinese martial arts and exercise, such as baguazhang, taijiquan (t'ai chi), and qigong (Chi Kung), as well as appearing in the pages of the I Ching.
Edo Neo-Confucianism Neo-Confucianism was brought to Japan during the late Kamakura period. It was spread as basic education for monks in training and others among gosan (Zen temples highly ranked by the government), while its theory was completed by annotations brought by the monk Yishan Yining, who visited Japan in 1299 from the Yuan Dynasty,[1][4] in the form of the Cheng-Zhu school of Neo-Confucianism. Moreover, Neo-Confucianist thought derived from the works of Cheng Yi, Cheng Hao, and Zhu Xi, and the then-orthodox ideology of China and Korea.[5] The rise of Neo-Confucianism in Japan was aided by state support from the Tokugawa government, who encouraged the establishment of national secular ideology as a method of strengthening political rule over the country.[1] The philosophy had arrived earlier in the 14th century, but knowledge of it was limited to Zen monasteries, who saw Confucianism as intellectually interesting, but secondary to Zen,[5] and some schools like the Ashikaga Gakko.
