Guan Lu (209-256 AD), courtesy name Gongming, was born in Guanzhuang Village, Pingyuan County (today, south of Shangjiamiao Village, Taoyuan Sub-district Office, Pingyuan County. During the reign of Emperor Kangxi of the Qing Dynasty, the Majia River burst and Guanzhuang Village was submerged. The villagers moved to Shangjiamiao to build a village). He was a famous medical practitioner during the Three Kingdoms period. He was proficient in Zhouyi and astronomy and geography. He was good at divination and the art of shooting covers, and was proficient in bird language. He was able to use the art of yin and yang to observe natural phenomena to predict the good and bad of things. He was a famous divination master in history and was revered as the ancestor by those who later generations who divinated and observed physiognomy. Guan Lu wrote 2 volumes of "Zhouyi Tongling Jue", 1 volume of "Zhouyi Tongling Yaojue", 1 volume of "Zhansuan Shu", 10 volumes of "Wuxing Zabujing" and 1 volume of "Niaoqing Nizhan", leaving a valuable cultural heritage for future generations. After his death, he was buried in the west of Zhoujiazhai Village, southwest of Pingyuan County, and south of Shangjiamiao Village. Most of Guan Lu's works have been lost, but many legends and anecdotes about the diviner Guan Lu are widely circulated among the people across the country. Representative ones include "Zhao Yan Seeking Longevity", "Guan Lu Shooting Covers", "Self-Calculation and Self-Destiny", "Guo En's Feast for Guests", "Magpie Reporting a Lawsuit", etc. These classic legends are recorded in "Records of the Three Kingdoms: Biography of Fangji", "Biography of Guan Lu" and "Romance of the Three Kingdoms". Chen Shou, the author of the Records of the Three Kingdoms, put Guan Lu's understanding and application of Zhouyi on the same level as Hua Tuo's medical skills and Du Kui's vocal music. Guan Lu's younger brother Guan Chen once wrote a biography of Guan Lu for his brother. There is a passage in it that is very important for us to understand Guan Lu: "(Guan Lu) also said that he had no wishes in this world, and he wanted to ascend the Lingtai with Lu Zishen, Zheng Bizao, Jin Buyan, Song Ziwei, Chu Gan Gong, and Wei Shishen, wear the divine map, walk on the three lights, understand disasters and anomalies, use yarrow and tortoise shells, resolve doubts, and have no regrets. Lu lived in the Wei and Jin dynasties, hiding his wisdom in simplicity, and he was flexible at times. He was not sought for his wisdom, and he was not abandoned for his stupidity. He could be said to be far away from others. Many people regard Lu as Jing Fang of the field, but Chen dare not agree. As for looking up at the stars, , he can predict good and bad luck, and he can predict the years in the long term and the days and months in the short term. He is not better than Gan and Shi in terms of his ability to predict the future. Dongfang Shuo is better at predicting the speed of the art of shooting at the cover. He can judge the nobility and inferiority by observing the shape of bones, and know life and death by observing the appearance and color. Xu Fu and Tang Ju are better than him. If he can understand the wind and explore the subtle weather, and understand the divine machine by listening to the birds, he is also a wonder of his generation. If he had been promoted to an official position and become a prime minister, his wealth would have flowed into the Ming Dynasty, and his brilliance would have been recorded in bamboo and silk, and all the mysterious experiences would have been mentioned, and all the secret words would have been left out. After a thousand years, those who have the Tao will surely believe in him and value him, while those who have no Tao will surely doubt him and be surprised by him. "The story of Guan Lu is well-known throughout the country. It is recorded in classics and widely circulated among the people. It has a far-reaching influence in the current Yixue community. Especially in the villages around Guan Lu's hometown, most people can tell a few stories about Guan Lu's divine machine. Zhouyi is a treasure of Chinese culture, and Guan Lu is a famous Yixue master in history. Strengthening the research on the legend of Guan Lu is conducive to promoting traditional culture and transforming Zhouyi culture from practice to cognition, then practice and re-cognition. This will drive the entire Zhouyi and its applied theory to achieve a qualitative leap and continuously promote the development of the application of Yi principles. "The Legend of Guan Lu" has been listed as an intangible cultural heritage of Dezhou City. Information source: Shandong Provincial Information Network (No pictures yet, welcome to provide.)
