Born at noon on February 15 in Gengshen, the second year of Yuanshou in the Western Han Dynasty, he was one year older than Jesus. The Eastern Han Emperor Zhang He died in Lingling's official residence on July 15 at the age of 89. All the dragon surnames in the world take the public as their ancestors, and the so-called ancestors refer to the earliest ancestors with pedigree to test. Because the genealogy of the dragon is synchronized with the year of A.D., it is natural and reasonable for everyone to unanimously recognize and inherit it forever, and to respect each other with one heart. Bo Gao Gong studies hard and is eager to become strong. At the beginning of Jianwu (32), it was the first mountain capital of Jinshi (now northwest of Xiangyang County, Hubei Province) and the official magistrate of Lingling County (now Yongzhou City, Hunan Province). When Bo was in office, he worked with Guiyang county magistrate in Luanba, dealing with government affairs while learning Taoism. Because they are court officials, they have a greater and deeper influence on the development of Taoism in Hunan than Fangxian Road in other places. The so-called Daoism is the general name of all the principles and methods about nature and society in ancient China. "Zhuangzi World": "The so-called Taoist in the ancient cloud, is the fruit evil? Say: everything is there. " Later Taoism (one of my people, formed in the Han Dynasty and prevailing in the Southern and Northern Dynasties) continued to refer to Taoist magic, or "magic". "Seven Seals of Yun Qi" (Volume 45) "The Secret of Law": "Tao is nothing but truth; The mysterious ci-poetry of the change of the performer is also. Tao is invisible, because technology helps people, and people are spiritual, and they will know it because of practice. " After leaving office, Bogaogong devoted himself more to studying Taoism. According to the true patent (14), Bo Gaogong was taught the method of childlessness from the immortal Taoist temple and often served the hungry side. Tuo Xing was drunk, lived in seclusion, and studied under Ding Lujun. The True Immortal Mirror and Taoism in Past Dynasties, Volume 5, said, "I don't know who the dragon is." In Jinshan, the spirit is as strong as a phoenix tree. If you treat it and serve it, you will seduce fesr. Served for two years, got a body and left. "Some details in Taoist books may not be true, but the fact that Bogaogong believes in Taoism is still credible. First, Ma Yuan himself has also learned some Taoist health preserving techniques: "At first, I will help you cross your toes and often feed you coix seed, and use it to relieve the combination of intellectuals, save your desire and overcome miasma". (Biography of Ma Yuan in the Later Han Dynasty) Birds of a feather flock together, and comrades in arms are close. Perhaps it is because they all have the same hobbies that they are so close and value each other so much. Second, in the Han Dynasty, the average life expectancy of Jin was only 28 years old, while that of Bo was 89 years old. Without special fertility treatment, it is difficult to live for so long. The secret of Taoist health preservation is nature, paying attention to inner cultivation and advocating quietness. However, it is reasonable for Bogao to live in a beautiful official residence with beautiful scenery and extremely rich natural vegetation, and to stay away from the world of mortals after retiring from politics. In addition, he has always paid attention to self-cultivation, "benevolent people live long."
