What does hundred schools of thought Zhongying Yang Family study?

On the view of nature, Yin and Yang scholars put forward the theory of universe evolution by using the concept of Yin and Yang in Zhouyi. From the division of Kyushu in Shangshu, the theory of "Great Kyushu" is put forward, and China is considered as a red China, with a small Kyushu inside and one of the "Great Kyushu" outside. In the view of history, the concept of five elements in Shangshu is transformed into "the end of five virtues", also known as "the transfer of five virtues" "Five virtues" refers to the attributes of the five elements, namely, earth virtue, wood virtue, kinder virtue, water virtue and fire virtue. According to Yin and Yang, everything in the universe corresponds to the five elements, each with its own virtues, and the operation of heaven, the changes of the world and the replacement of dynasties are the results of the "five virtues transfer". Its purpose is to demonstrate the social changes at that time. In terms of political ethics, the Yin and Yang scholars believe that "benevolence and thrift are the only thing, and the monarch and the minister are the six relatives" and agree with the Confucian theory of benevolence and righteousness. At the same time, it emphasizes that "due to the great harmony of yin and yang" contains some knowledge of astronomy, calendar, meteorology and geography, which has certain scientific value. At the beginning of the Han Dynasty, the Yin and Yang school still existed. After Emperor Wudi's strike of 1 schools, some contents were integrated into the Confucian ideological system and some were absorbed by primitive Taoism. As an independent school, the Yin and Yang school disappeared. Representative figures: Zou Yan, Zou Yan (about 35 BC to 24 BC), a native of Qi State (now Linzi, Zibo City, Shandong Province), a representative figure of the Yin and Yang families, was known as Tan Tianyan, also known as Zou Zi, because of his pedantic knowledge. His deeds recorded in the old history are false, but it is certain that he came from the late Warring States period. Zou Yan once studied in Jixia Xuegong, and valued learning more than qi. To Wei, Wei Huiwang suburbs to meet. When I arrived in Zhao, Ping Yuanjun treated me as a guest and host. To Yan, Yan Zhaowang personally swept the dust in front of him, listened to his lectures, built kesh Palace for him, and held a disciple ceremony. Therefore, it is speculated that he may have died after the battle of Changping. Zou Yan's works "Zou Zi" and "The End of Zou Zi" are said to have more than 1, words, but they have long been lost. At present, only some paragraphs in Lu's Spring and Autumn Annals and Sima Qian's Historical Records can show his thoughts.
