The Yinyang guanjian 陰陽管見 "Humble opinions on Yin and Yang", also called Yinyang guankui 陰陽管窺, is a book on divination compiled by the Ming period 明 (1368-1644) master He Tang 何瑭 (1474-1543), courtesy name He Cuifu 何粹夫, style Baizhai 柏齋 . He came from Wuling 武陵, Henan, and obtained his jinshi degree in 1502. He was made bachelor (shujishi 庶吉士) at the Hanlin Academy 翰林院, later junior compiled (xiuzhuan 修撰). He was then appointed prefect (tongzhi 同知) of Kaizhou 開州, then of Dongchang 東昌, and then rose to the office of vice education-intendant censor (? tixue fushi 提學副使) of Shanxi. He crowned his career with several high posts in the secondary central government of Nanjing 南京, first as Vice Minister in the Court of Imperial Sacrifices (taichang shaoqing 太常少卿), then as director (langzhong 郎中) in the Ministry of Works (gongbu 工部), then of Revenue (hubu 戶部) and of Rites (libu 禮部), and finally as Right Censor-in-Chief (you duyushi 右都御史). His posthumous title is He Wendinggong 何文定公.|
The short text is a scientific revision of the Neo-Confucian paradigm of the "primordial matter" (yuanqi 元氣) and its divergence into the two matters Yin and Yang. He Tang explains that Yin and Yang are void names, and that only Heaven and Earth, water and fire exist, from which all ten thousand creatures emerge. These elements have many different states. Water, for instance, can be vapour, swamps, or coldness, while fire can be expresses by heat, warmth or splendour. The spirit of Heaven is expressed in intelligence, that of the Earth in the shape, while fire and water also contribute to the formation of personality. The four "elements" are mixed to a coherent entity, but nevertheless act so clearly that no disorder results. Heaven is thus dependent on the Earth, and fire on water, and vice versa. A mutual production of these elements is impossible, like it is assumed in the five-processes theory (wuxing 五行), where one element or phase produced the next one in a kind of productive cycle (wuxing xiang sheng 五行相生).
The book is to be found in the collectanea Bailing xueshan 百陵學山 and Xuehai leibian 學海類編.
