Dong is of the same ancestry, and all of them are descendants of Emperor Zhuan Xu of Levin. According to historical records, Dong's surname originated in three places: northern Dingtao, southwestern Shanxi, and Pingyuan County, Shandong Province. During the Qin and Han Dynasties, Dong Shi was mainly concentrated in Shanxi, Gansu, Hebei, Henan and other places. In addition, there are Dong clan members scattered in Shaanxi, Dingtao and Gaoqing in Shandong, Guangzhou in Guangdong, Ziyang and Deyang in Sichuan, Yuyao in Zhejiang, Xiangyang and Zhijiang in Hubei, Fuzhou in Fujian, Yuzhou, Yichuan, Nanyang, Kaifeng, Qixian, Xinyang and Lingbao in Henan. Later, in the process of continuous reproduction, Dong in Gansu and Shandong developed into a local aristocratic family. During this period, according to historical records, the reproduction and migration of the population in Dong Shi are as follows: Kun, a descendant of the Taishi branch of the State of Jin, was named Zhai Wang and became a slave (now on the east bank of Dongyanhe River in Yan 'an City, Shaanxi Province), and his descendants moved to Longxi (now Lintao, Gansu Province); Dong Zhongshu was a native of Guang Chuan (now Zaoqiang East, Hebei Province) in the Western Han Dynasty. His great-grandson moved from Guang Chuan to Longxi, and later generations moved to Hedong (now northwest of Xiaxian County, Shanxi Province). During the Wei, Jin, Southern and Northern Dynasties, the society was in turmoil, and people were scattered everywhere and moved southward on a large scale. Dong migrated from Anhui, Jiangxi, Jiangsu, Hubei and the middle and lower reaches of the Yangtze River. During the Sui and Tang Dynasties, Dong Shi was a period of great reproduction, and there were Dong Shi emigrants in Fujian and Guangdong. In the Tang Dynasty, people from Gushi (now Henan), Wang Chao and Wang entered Fujian with Dong Shi. During the Song and Yuan Dynasties, the Nomads entered the Central Plains, and the southward migration of Mongolian troops forced Dong to move southward again. At this time, the Dong Shi clan appeared in Yuhang, Zhejiang. During the Ming and Qing Dynasties, there were Dong residents in Taiwan Province Province, Nanyang Islands and some countries and regions in Europe and America, and Dong people in this period were all over the world. Today, Dong's surname is mainly concentrated in Hebei, Shandong, Shanxi, Yunnan, Liaoning, Zhejiang and other provinces. Hebei, Henan and Shanxi provinces account for 3 1% of the total Dong population, while Yunnan, Shandong, Liaoning, Zhejiang, Sichuan and Hubei provinces account for 38%. Hebei is the largest province, accounting for 1 1% of the total Dong population. Dong is the 29th surname in China with a large population, accounting for 0.6 1% of the Han population in China.

Dong Zhongshu used to be an official in Shandong and a foreign minister. Although his time was short, he left many descendants. Dong An, the son of Dong Zhongshu, moved back to Longxi from Guang Chuan, and his grandson moved back to Hedong, from Yuan Dynasty to Mindfulness (1341-1369) for 28 years, to Hongwu in Ming Dynasty (1369 to137/). This tribe gathered from Shandong to Gezhen 'gou, Yandun Village, Mayi County, Shuozhou, and moved to Zizhen County, Xinzhou in a certain year from 1369 to 137 1 year (credible by 1369). In the history of Dongshi, Shanxi Province, there were people who climbed officials and generals. A piece of archaized General's epitaph was found in the field archaeology, and all the people who climbed officials were recorded in the genealogy.
