One saying is that since Shun's politics was clear and immortal, the descendants of Shun were sealed in Chen (now Henan Province) at the beginning of the establishment of the Zhou Dynasty. At the end of the Spring and Autumn Period, Chen declined, and Chen Wan, the royal family, ran to Qi, taking Tian as his surname (Tian and Chen were given leave). After years of pioneering, the clan prospered again, and was charitable. When lending food to others, it used a big bucket, and in the future, it relied on a small bucket to pay off debts, gradually gaining the trust of Qi people. In the end, Jiang's family (a descendant of Lu Shang) became the master of Qi. After Tian's family came to Yan, at the end of the Warring States period, there was a chivalrous man who dared to do what was righteous, that is, the source of Zhao's surname, the ancestor Tian Guang. Tian Guang, excited by indignation, introduced Jing Ke to Yan Taizi Dan, but Jing Ke failed to stab the king of Qin, which was a drain. After Qin destroyed the six countries, investigate the case thoroughly. Later generations of Tian Guang took their father's name as their son's surname, and avoided Shanxi (temporarily suspecting here, pending the approval or correction of Guang's surname with genealogy), so Jiang County (now in Shanxi Province) was the county hope. At the end of the Yuan Dynasty, there was chaos in the world, and Shandong and other places were empty, but Shanxi was peaceful and populous. The establishment of the Ming Dynasty forced Shanxi people to emigrate to Shandong, Anhui and other places, that is, the "big locust tree immigrants" in history, and the people surnamed Guang were among them. Except for those who lived in Shanxi, a genealogy of Guang's family who went to Shandong is recorded, and the rest are unknown. One branch of Yangxin in Binzhou, Shandong Province is roughly as follows: During the Hongwu period of the Ming Dynasty, it moved to Shandong from Leping, Shanxi, and lived in Daguang Village, Liupowu Town, Yangxin County. Ancestors are loyal and loyal, and practice medicine to help the world and benefit one side. In the second year, Guang Hongzu was once the General Sima of Nanjing Ministry of War in Ming Dynasty (in doubt), and he was located in the military tomb in the west of the village. (It is said that a heart protector was unearthed a few years ago, which needs to be verified); Guangmao, the fourth ancestor, once served as Zuo Shenzheng in Henan. (The official title is to be checked. It is said that there are also Guangzu people in Zhuqu Town, Weishi County, Kaifeng, expecting mutual authentication.) Yi is located in Wuli, the north of the village, south of Zhangtie Village. Before the Cultural Revolution, there were relics such as stone figures and horses. The old school in the village once took a stone tablet (not checked). Now the Shinto in front of the tomb has disappeared, leaving only two silk portraits of Guangmao's ancestors. Because of its age, it is responsible for future generations. The fifth generation of light deepened the Ming ancestors, and the words were bright. He is a great calligrapher and good at flower-and-bird painting. The county museum has a pair of couplets, leaving a word worth a thousand dollars and other good reputation. The sixth generation of Guangchu Qizu was good at writing poems. Now his genealogy contains nearly 1 poems, and he wrote the book Dan Zhidan. In Daguang Village, there is a handwritten genealogy of Guangxu Year in Qing Dynasty (* * * four volumes)
Another way of saying it is: a surname was unable to bury its ancestors because of poverty. Before the local officials came to explore the boundary, they first told the children playing nearby that if someone asked, they would call the place an ancient place of light, and the family name of light was changed from now on. This surname of light was based on Tongcheng. Because the earliest people who lived in Tongcheng were two brothers who lived in Hedong and Hexi, they were called Dongguang and Xiguang. From the Ming Dynasty, the Qing Dynasty to the Republic of China, Tongcheng Guangxing was a local noble family, and its descendants were further famous for their eagerness to learn. They were called "the family of scholarly family and the home of osmanthus"
