The compass was invented by Yang Gong.
2. Compass is a tool for feng shui detection, and it is a common operating tool for managing style. The compass is mainly composed of a magnetic needle in the center of a disk and a series of concentric circles, each of which represents the ancient people in China's understanding of a certain level of information in the cosmic system.
3. As the founder of Feng Shui in Yang Gong, Yang Gong, a native of Gannan, not only established a complete theory of Feng Shui, but also reformed the Feng Shui compass. In 854, Yang, who was only 20 years old, became a scholar of Ke Di. In Tang Xizong, this official is Dr. Jin Guanglu of the imperial court. He is responsible for the geography of Lingtai, the planning and layout of palace buildings and important temples, as well as astronomical observation and royal sacrifices. In 875 A.D., Huang Chao started fighting, and in 880, Chang 'an, Kyoto, fell. In order to avoid the disaster of Enemy at the Gates, Yang fled Chang 'an with the imperial secretary Guo Pu's Tomb Book (Secretary of Forbidden Jade Book). After running around, he fled south to Chongxianli, under the jurisdiction of Ganzhou Prefecture, and stayed at Huang Chan Temple.
4. The Twenty-four Mountains Plate was created by Yang Gong. Before Yang Gong, there were no complete twenty-four mountain plates, only eight diagrams plates and twelve branches. Although the compass of the Han Dynasty also has the marks of "Eight Diagrams", "Earthly Branches" and "Heavenly Branches", it does not divide the degrees equally, but divides the heavenly stems, eight diagrams and twelve earthly branches into three layers with different degrees. Yang Gong rearranged it, and completely distributed Bagua and heavenly stems and earthly branches on the plane, which was an epoch-making creation.
5. The astrolabe of the Twenty-four Mountains, or the Seventy-two Dragon Pan, was created by Yang Gong in his later years. Through long-term exploration and practice, Yang Gong found that Yin-Yang and Five Elements generally exist in all directions, and the distribution of Yin-Yang and Five Elements according to the attributes of Eight Diagrams and Five Elements is not consistent with the actual situation. It's too rough to use yin and yang dragons as dragons. Through repeated research, the twelve earthly branches and heavenly stems are matched to express the attributes of the dragon, which is called "upside down" five elements. In the "Green Capsule Austrian Language", "upside down, there are jewels on the 24 th Mountain; On the other hand, there is a fire pit on the twenty-fourth mountain, and this "upside down" refers to the seventy-two dragons in Yin Na's five lines.
This is about who invented the compass.
