What is "exchange"?
The style of Yuanbao Biography in the Northern Zhou and Wei Dynasties is similar to that of Taiyuan (Xuan), and the sequence is Guizang (a summary of Yuanbao Biography in Sikuquanshu). Although Fang's Jing Jia Yi Jing is in the name of Yi Chuan, it never understands the Jing and does not echo Yi Chuan ... So Xiang Anshi said that it was easy to test in Beijing, and the book Huozhulin handed down from generation to generation is its legacy ... Zhang Xingcheng also said that Wei's method is in line with Huozhulin and Huozhulin. In the Song Dynasty, Zhu wrote Essentials of Iraq's Three Norths, including Lianshan and Guizang. It is said that Lianshan used divination to judge good or bad luck. The method of "fire bamboo forest", that is, the method of using heavenly stems and earthly branches to cooperate with divination to break good or bad luck, originated from the first meridian and was close to "returning to Tibet"; Yuan Bao and Ghost Hide are on the same level. In the Northern Song Dynasty, Shao Yong wrote "Huang Ji Jing Shi", and Zhang Xing became a cloud: "The innate person is Fuxi Yi; The day after tomorrow, wang wen also relaxed. "Taiyuan (Xuan)", Ziyun (Yang Xiong) Yi, the horse of the day after tomorrow; Huang Ji Jing is the Yijing and congenital inheritance of Kang Jie (Shao Yong). " ("Sikuquanshu Huangshi Suoyin Original Preface") If there is no innate Fuxi, how can there be a "congenital heir"? Therefore, we can say that Lianshan and Guizang were still circulated in the Song Dynasty, and they were only collected by full-time staff, so it is difficult for ordinary people to see them. Or because of the relationship between teachers and students, it is scattered among the people. In this case, the "Ancient Three Graves" inscribed by Ruan Xian and A Jin were discovered among the people in the Northern Song Dynasty. Isn't it natural? Therefore, just because "Three Graves" is not Huang San's original work, it cannot be said that it is made out of nothing and has no credibility. In fact, the "Three Graves" must have been written by someone who knows what happened. Because, after all, Zhou Li and other books have mentioned two books, Lianshan and Guizang, and what is missing is Gankun. From the specific analysis of hexagrams, it can be unified with the historical background of the "Huang San" era. Therefore, the "three graves" are not completely untrustworthy. Why didn't the ancient three graves spread widely and had little influence? First of all, because the age is too long, the characters are inevitably obscure, and the Book of Changes and Yuan Baojing are still obscure, not to mention the three ancient tombs. Secondly, the calendar represented by the Yellow Emperor Gan Kun was opposed by several dynasties and was replaced by Zhouyi in Zhou Wenwang, so it was not mentioned by later generations. Third, the ancient three graves were originally books about emperors ruling the world, discussing longevity and predicting good and bad luck, but they were still in the hands of the state in the Western Zhou Dynasty, so it is difficult for ordinary people to read them. Fourth, I don't know how many cultural relics and classics were destroyed by the catastrophic floods in the Yao, Shun and Yu era. Fifth, wars are frequent, and books can't escape their disasters. Sixth, the Qin Dynasty burned books to bury Confucianism. "It was not the Qin Dynasty that burned them, nor was it the post of doctor. There are hundreds of people who collect poems and books in the world, and they know it. "... those who don't go, the book of medical divination. "("Historical Records of the First Qin Emperor ") As a book of" Yan Avenue ","Gu San Fen "is of course difficult to preserve. Finally, Xiang Yu burned Epang Palace and the books hidden by Dr. Qin Seventy-two. Liu Dakui said: (Although the book was burned in the Qin Dynasty), the hiding place of the doctor was there, and it was never burned. Xiang Yu entered the customs, killed Qin, surrendered, took their treasures and women, and burned Qin Gong. The fire in March did not go out, but the legal system of Tang Yu's three generations, the quips of ancient sages and sages, began to swing into ashes. Yesterday, I went to Xianyang from Xiaohe to collect the imperial edicts of Prime Minister Qin, and the books hidden by Dr. Qin were treasured without listening to them. If Xiao He could collect the legal books and hide them, Xiang Yu would not have burned them, and the whole classic of the sage was still there. (The debate on burning books is quoted from Liu Yizhi's Cultural History of China, p. 300.) Now, in addition to the Han and Wei series, there are 21 kinds of secretaries and masters in this book. Here I would also like to talk about the relationship between the "Three Tombs" and the Xia, Shang and Zhou Dynasties. Zheng Xuan quoted Du Zichun as saying: Lianshan is a drama, and Return to Tibet is the Yellow Emperor. (See "Notes on Zhouyi", p. 80 1) But Zheng Xuan also said: Lianshan is in summer, hiding in the shade, and Zhouyi is in the week. (this is the "three changes", plus the Book of Changes and the preface to the Book of Changes, see page 9 of the Notes to the Thirteen Classics.) Then, why is there such a statement? According to Professor Zheng Zhongying of the University of Hawaii in the United States, this problem can be explained as follows: If we represent the beginning of the fishing and hunting culture in Fuxi era, hunting in the mountains and fishing by the water are obviously the experience basis of Lian Yi Shan; If the Shennong era is regarded as the representative of the beginning of agricultural culture, it is obviously the empirical basis for returning to Tibet. Judging from the history of civilization development, Lianshan and Guizang can be associated with Fuxi and Shennong. Of course, this statement does not necessarily conflict with the statement that "even the mountains and summers are hidden in the shadows." This is because Xia people can inherit Lianshan Yi because of their fishing and hunting background, and Yin people can inherit Tibetan Yi because of their farming background.
