Who were Jiao Yanshou's apprentices in Han Dynasty?

Jiao Yanshou (the year of birth and death is unknown), a famous philosopher in the mid-Western Han Dynasty.

When Emperor Zhao of the Han Dynasty, Jiao Yanshou came out as an official, and his political achievements were very good. Later, while teaching, he wrote books, including Jiao's Yi Lin, and concentrated on reading, especially the Book of Changes. On behalf of the apprentice, there is a Beijing room.

Jiao Yanshou claimed to learn from Meng Xi in Zhouyi, and his student Jing Fang also thought that "Yanshou was easy to learn from Meng Qian". Meng Xi told his disciples that Qu Mu and Bai Sheng refused, but they all said no. In fact, "Jiao Yanshou's hermit theory is different from Meng's hermit theory". "It is said that it is longer than disasters, and it is divided into sixty-four hexagrams. It is more straightforward to use things, and each has its own experience." These thoughts were later inherited and developed by his disciple Jing Fang, a famous Yi-ology scholar in Han Dynasty.

Jiao's Yi-ology works include Lin Yi and Lin Yi Bian. There are sixteen volumes in Jing Ji Zhi and thirty-two volumes in Liang Ji Zhi. Sixteen volumes of Lin Yi Debate Exhibition. Classic Old Tang Shu contains sixteen volumes of Jiao Lin Yi, which are also recorded in New Tang Shu and Song Shu. Today, Jiao's works include.

Fang (77-37), a scholar of the Western Han Dynasty, was born in Dunqiu (now southwest of Qingfeng, Henan Province). He studied under Jiao Yanshou from A Liang. Jiao Yanshou claimed to learn from Yi and thought that Jiao Yanshou's Yi was a study of Mencius, but his disciples Bai Sheng and Zhai Mu disagreed. Jiao Yanshou often said, "The deceased was born in Beijing after learning from me." Jing Fang said that the Book of Changes is longer than cataclysm, and it is divided into sixty-four hexagrams, which is more straightforward for daily use, and each has its own experience. In the fourth year of the Yuan Dynasty (the first 45 years), Emperor Hanyuan was promoted to Lang, and later served as the magistrate of Wei County. On many occasions, I talked about disasters and quoted the Spring and Autumn Annals and the Book of Changes, which offended the eunuch Shi Xian, ran counter to the powerful five deer theory that ruled the Book of Changes, and was abandoned on the charge of "not slandering politics and returning to the evil son of heaven". [1] Later, Fang Jing's three disciples, Yin Jia, Yao Ping and Cheng Hong, were all doctors in Confucian classics, so The Book of Changes included Confucian classics. Fang Jing has three volumes of Yi Zhuan, ten volumes of Zhouyi Zhang Ju, seven volumes of Zhouyi hexagrams, twelve volumes of Zhouyi Ci, twelve volumes of Zhouyi Zhanshi, three volumes of Zhouyi Shoulin, nine volumes of Zhouyi Hou Fei, eight volumes of Zhouyi Houfei Six Days and Seven Points, and Zhouyi Shi Si.

In the history of science, Fang Jing's position also benefited from his musical attainments. It is not an exaggeration to say in Biography of Fang Jing that he "has a good clock rhythm and a bosom friend". His surname is Li, and it is inferred that his surname is Jing (Biography of Han Shu), so he takes Beijing as his surname. This incident fully shows his fascination with melody.

In the aspect of melody theory, Fang Jing expanded the traditional twelve rhythms into sixty rhythms. Prior to this, people used the three-point profit and loss method to calculate the twelve laws. In this way, after the eleventh child (that is, the twelfth law), they can't return to the original law, so the twelfth law can't be repeated. In this regard, Fang Jing adopted the solution of extending the Twelve Laws. According to the traditional three-point profit and loss method, Huang Zhongsheng Lin Zhong, Lin Zhongsheng are too clustered, and Lu Nan are too clustered, so that they are born in turn, and finally they are born in the middle, and they get twelve methods. Fang Jing lived from Middle Road to Sixty Laws. In fact, Jing Fang didn't invent the Sixty Laws. It is clearly recorded in the Laws of the Later Han Dynasty that the Emperor of the Han and Yuan Dynasties sent respect to each other and asked Fang's laws and regulations, "Sixty Laws of Fang Sheng and Jiao Yanshou". Therefore, Sixty Methods is the work of Jiao Yanshou, and the function of Fang Jing is to introduce this method to the society.

By adopting the law of 60, when it rises to 53 times (that is, the law of 54), it is very similar to the law of departure and can be repeated. However, in order to combine the law with the calendar, Jiao Yanshou and Jing Fang must make up an integer of 60, so that "the yellow bell starts from the winter solstice and returns from the winter solstice on the day when the sixty laws are phased." (The Book of the Later Han Dynasty) This is of course far-fetched. Moreover, this method is difficult in playing practice and making musical instruments, and has no practical value. The value of this legal method lies in that it theoretically points out a possibility for people: the melody can be changed through a slight sound difference.
