What is the World Disk?

Huang Daozhou (1585~ 1646) was born in Tongshan, Zhangpu (now Dongshan). In the second year of Emperor Mingxi's reign of Apocalypse (1622), he was a scholar, changed to Jishi Shu, and was appointed editor-in-chief. Long military attache to Wu Yingdian university student, Ministry of War history. He has been in the DPRK for more than 20 years and has been on the sidelines for more than 30 times. History books say that he "refers to Chen, keeps his talents, is unfaithful, and deeply abuses the times." He has been demoted many times because of his harsh words.

When the Qing soldiers entered Shanhaiguan and Nanjing fell, he gathered more than 9,000 rebels in his hometown to support the Tang Dynasty King Zhu against the Qing Dynasty. He was immediately defeated by Wuyuan and captured to Jiangning. The Qing court seduced him in every way. However, Daozhou persevered and did not die for seven days, and was finally killed on the fifth day of March. 1646. It is said that the day before his death, an old friend "held wine, vegetables and tactics" and even drank very well as usual. After getting up and changing clothes, he calmly made a long scroll of calligraphy and painting to give to a friend who asked him for ink the other day. He gnawed his finger and wrote a bloody book "Never forget, be loyal for a thousand years, know my world, and don't worry about my family". Today, he generously died outside Donghua Gate in Nanjing. Really upright and noble! Cai Shiyuan, the master of Qianlong, once compared Shao Yong, Li Gang and Wen Tianxiang to Huang Daozhou, which has been a conclusion for almost 300 years.

Huang Daozhou is well-read, sensitive to articles and poems, good at painting and astronomical laws, so there are many scholars gathered there. He wrote a lot in his life, only Fujian Tongzhi? There are more than 30 bibliographies of his works in Yiwenzhi. Scholars in poor years can't understand Yi, Dong Ji and Jing.

Just in the courtyard of Mingchengtang in Zhangpu, there is also a disk of heaven and earth, also called Arabic map, all made of granite, which is a desktop. It is divided into two layers: the lower layer is the platform base, and the upper layer is 3.7 meters long and 0.42 meters high. Each side of the disk is engraved with 128 small squares, 5 12 squares a week, and the whole is 16384 squares. Between the squares, eight concentric circles are carved from the inside out to represent "heaven" and the squares represent "earth", hence the name "heaven and earth disk".

It is generally believed that the disk of heaven and earth was specially designed by Daozhou to talk about the Book of Changes. Some people think that it is based on the principle of "Fiona Fang tangency, which becomes flat every eighteen years", so as to measure the weather's sunny or sunny, the omen of the change of the 24 solar terms, etc., but no one speaks a truth about the specific operation. Now this big stone has become a mystery, and no one knows why. Guess it must contain complicated relationships in all aspects, which can only be explained in the dynamic. It's amazing that Huang Daozhou's observation and understanding of the relationship among three people, land and people 300 years ago was so profound!
