Yang, a aristocratic family of Hongnong, is a Yang family whose county is hongnong county (Huayin County, Shaanxi Province). His ancestor is Yang Chang, the prime minister of the Hanzhaodi period and the son-in-law of Sima Qian.

Yang Zhen, the great-great-grandson of Yang Chang, was the official residence of Taiwei in the Eastern Han Dynasty, known as "Confucius in Kansai", and his sons Yang Bing, Sun Yangci and great-grandson Yang Biao were all Taiwei, known as "Taiwei IV" and "Tokyo Famous Family". According to the documents such as the Book of the New Tang Dynasty, the Prime Minister's Genealogy Table, and the Annals of the Clans, Yang Hongnong originated from Ji's surname, and belonged to the sheep tongue of the Duke of Jin, who was a teacher and uncle.

The native place of the Yang family of Hongnong is Huayin County, hongnong county (now Huayin East, Shaanxi Province). Similar to other gentry, after several generations, they still call themselves as Huayin people of Hongnong.

As an aristocratic family in the Eastern Han Dynasty, Yang Hongnong did not successfully transform into a famous aristocratic family in the Wei and Jin Dynasties. At the end of the Eastern Han Dynasty, Yang Biao and Yang Xiu, the sons of Yang Bing, were suspected and even killed because of their loyalty to the Han Dynasty.

In the Western Jin Dynasty, the brothers Yang Jun, Yang Huan and Yang Ji, who were exclusively consorts, soon failed and were punished by the three clans. During the Eastern Jin Dynasty, Yang Liang and his son were ostracized because of "crossing the river late, and their marriage and official were out of class", and they became abandoned military commanders who "took jobs by force", and were finally killed by Huan Xuan and Emperor Wu of Song Wudi.

according to the textual research of scholars such as Tang Changru, Li Wencai and Wei Hongli, the descendants of Yang Zhen, the commander of the Eastern Han Dynasty, could not be traced back to the Northern Wei Dynasty. The young people who have been promoting agriculture since the Northern Dynasty, such as Yang Zhen, Yang Bo, Yang Jun (Yuegongfang), Yang Xiong (Guanwangfang) and Yang Huituo-Emperor Wen of Sui, are recorded in the Book of the New Tang Dynasty.

Origin

With the demise of the State of Jin, the "difficulty of praying for profits" disappeared. Without political obstacles, the Yang family developed and expanded. According to the information provided by Huayin Yang's Cultural Research Association, after Yang walked out of the forest from Yangdao and re-entered the political arena, more than ten generations were Zhou's officials, or doctors, Sima, or teachers and state shepherds.

At the end of the Qin Dynasty, Huayin Shuo Yang led eight of his sons to fight with Liu Bang. His sixth son, Yang Xi, was awarded the title of Red Spring Hou for his meritorious service in killing Xiang Yu, while the other seven sons were all named generals, and Shuo Yang himself was named Taishi. Sun Yang, the fourth generation of Yang Xi, became prime minister and married Sima Ying, the daughter of Sima Qian, the Taishi Duke.

At this time, Hongnong Yang was in the imperial court, with a rank of Lieqing and a rank of Tong Hou, and ten people took Zhu Lun, which was called "Ten Wheels of the Western Han Dynasty" in history. Before the age of 5, Yang Zhen in the Eastern Han Dynasty studied the classics in poverty, set up a museum to teach disciples, and called it "Confucius in Kansai". Later, he became an official, and the official was Situ and Taiwei, who was honest and clean, and was called "innocent official" in history; His sons, Yang Bing, Sun Yangci and great-grandson Yang Biao, all inherited the legacy of Yang Zhen, and were all officials to Qiu, and were called "Three Fairs of Eastern Han Dynasty IV" by later generations.

Since then, Yang Hong-nong has also been a talented person in successive dynasties, such as the "Three Yang in the Western Jin Dynasty" who took charge of the military power in Wei and Jin Dynasties; Yang Bo brothers, the official family in the Northern Wei regime; In the Tang Dynasty, the four surnames "Li Wu Wei Yang" were married to Yang's "Eleven Prime Ministers' Family" in the political group, Yang Jiajiang, who was full of loyalty in the Song Dynasty, and Cheng Dayan, who was a Dali Temple in the Southern Song Dynasty. Their family legacy, which was initiated by Yang Zhen in the Eastern Han Dynasty, and Yang Jiajiang's loyalty to serve the country, had a far-reaching impact on later generations.

During the Eastern Han Dynasty, the Yang family who lived in hongnong county started from Yang Zhen (59-124) and was re-elected as prime minister for the fourth time, becoming a local noble family. Yang Zhen was an honest and respected official. On his way from Jingzhou secretariat to Donglai satrap, Wang Mi, the county magistrate of Changyi (now Juye County, Shandong Province), felt grateful for his "Chaju" (official selection system in Han Dynasty) and prepared ten Jin of gold for Yang Zhen at night.

Since then, Yang Zhen's famous saying "Heaven knows, God knows, I know, you know" came into being, and Yang Zhen was called "Mr. Four Knows" by later generations. Hongnong Yang, from now on, also regarded Yang Zhen as the ancestor of Kaiji, and took the hall name "Four Knowing Hall".
