One view is that at the beginning of the establishment of the Zhou Dynasty, the descendants of Shun were sealed in Chen (now Henan Province) because of their political clarity and immortality. At the end of the Spring and Autumn Period, Chen declined, and the royal family Chen Wan went to Qi State to take Tian as his surname (Tian and Chen were granted leave). After years of development, the family has prospered again, and is charitable. When lending others food, they used big barrels, and later they paid off their debts by small barrels, gradually gaining the trust of Qi people. Finally, the Jiang family (the descendant of Lu Shang) became the master of Qi. After the Tian family came to Yan State, at the end of the Warring States Period, there appeared an aggressive chivalrous man, who was the source of Zhao's surname and the ancestor Tian Guang. The indignant Tian Guang introduced Jing Ke to Yan Taizi Dan, but Jing Ke failed to stab the king of Qin, which was a disappointment. After Qin destroyed the six countries, investigate the case thoroughly. Later generations, Tian Guang took his father's surname as his son's surname, avoiding Shanxi (it is doubtful here, and the genealogy is to be approved or corrected by Guang's surname), so Jiang County (now Shanxi) is the county hope. There was chaos in the world at the end of the Yuan Dynasty, and there was no one in Shandong and other places, but Shanxi was peaceful and had a large population. 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 people with wide surnames were among them. Except those who lived in Shanxi, there is a genealogy record of Guang's family who went to Shandong, and the rest are unknown. A branch of Yangxin in Binzhou, Shandong Province is roughly like this: During the Hongwu period of the Ming Dynasty, it moved to Shandong from Leping, Shanxi, and lived in Daguang Village, Liupowu Town, Yangxin County. Grandfather is loyal to the monarch, practicing medicine to help the world and benefit one side. In the second year, Guang Hongzu was Sima (doubtful), the general of Nanjing Ministry of War in the Ming Dynasty, and 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. The fourth ancestor was Zuo Ren. (Official title to be determined. It is said that there are also Guangzu people in Zhuqu Town, Weishi County, Kaifeng, looking forward to mutual authentication. ) Iraq is located in the north of wuli village and the south of the village. There were stone statues, horses and other relics before the Cultural Revolution. 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 Guang Mao's ancestors. Because it is so old, we should be responsible for future generations. The five generations of light deepened the Ming ancestors and the words were bright. He is a great calligrapher and is good at flower-and-bird painting. The county museum has a pair of couplets, leaving a good reputation such as a word of gold. The seventh ancestor of Chu Guang, the sixth generation, was good at poetry creation. Now his genealogy contains nearly 100 poems, and he also wrote the book Dan Dan. Daguang Village has a handwritten genealogy (* * * four volumes) of Guangxu period in Qing Dynasty.
Another way of saying it is that a surname cannot bury its ancestors because of its poor family. Before the local officials came to explore the boundary, they told the children who were playing nearby to predict that if anyone asked about a place, they would call it the land of light people and ghosts. Afterwards, they were willing to change their surnames. This surname of Guang originated from 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 famous local family, and its descendants were even more famous for their eagerness to learn. They are called "the home of scholarly books, the hometown of osmanthus"
