青囊经
最早的风水典籍
The Green Sachet Classic- the earliest book on Feng Shui
第一本有文字记载的风水经书是秦末汉初黄石公所著的《青囊经》。在中国古代哲学体系下，《青囊经》确立了“风水学”的具体哲学思想和理论体系。黄石公以后的风水师们则在此理论体系下进行技术上解释和附会，并逐步使风水术驳杂、晦涩和神秘。

The first geomancy classic names "The Green Sachet Classic" (青囊经) is the very first book on Feng Shui and author by Huang Shi Gong (黄石公) during the early Qin秦 dynasty. "The Green Sachet Classic" doctrine was established and incorporated in the ancient Chinese philosopher's thought and mind as a fundamental theory that one should understand and practice. However, after Huang Shi Gong, the later Feng Shui master does not have the skill and ability to carry on his approach and system. Instead, they explain and make it confusing, contradicting, and complicated, and even resort to tricks. Thus, gradually it causes the theory and doctrine to be challenging to read, understand, and become mystical.

上卷 化始

In the First scroll, the change begins
 
天尊地卑，陽奇陰偶。一六共宗，二七同道，三八為朋，四九為友，五十同途。

Heaven is honorable, and earth is the follower. So the Yang gives orders, and the Yin follows.
Jia甲 as one and Ji己as six, have common ancestor, Yi乙 as two and Geng 庚 as seven are from the same path, Bing丙 as three and Xin辛 as eight are friends, Ding丁 as four and Ren壬 as nine are good friend Wu戊 as five and Gui 癸 as ten came from the same route.
 
闔闢奇偶，五兆生成，流行終始；八體弘布，子母分施。

When the Yang and Yin are joined and pair up, the five signs of birth are completed, and they move and flow in the same fashion from beginning to end. When the element takes its shape and is formed, the child is born.
