During the Qin and Han Dynasties, people in the State of Qi were cunning and liked to cheat and hurt others secretly. There are related records in Historical Records that the country of Qi, Fake and Bullying is changeable, and the country is also restored. There are also related records in Hanshu, that is, words and deeds are inconsistent and deceitful. This also shows that Qi people are cunning, inconsistent in words and deeds, and fickle. Therefore, in the Qin and Han dynasties, Shandong people presented themselves in front of history with such a gesture, rather than the image of a big man in Shandong.
By the Ming and Qing Dynasties, Shandong people were no longer sinister, which was related to the historical environment of Shandong at that time. At that time, the fixed songs in the Yuan and Ming Dynasties caused some exchanges between people in Shandong and other regions, which led to the mixed population in Shandong. In this way, people from other regions mixed in, and the image of Shandong people changed. At the end of the Yuan Dynasty, due to the perennial war in Shandong, Shandong people moved out, and fewer and fewer people stayed in Shandong.
The title of Dahan is mainly related to the heroic uprising of Wagangzhai in Sui and Tang Dynasties. At that time, all the people who revolted were Shandong people, such as Qin Hecheng, who were all strong men. Because this uprising is famous in history, and its heroes are well-known in history, people began to label the image of Shandong people as big shots. Later, during the Song Dynasty and the revolt of Liangshan heroes, many people were from Shandong, and their bodies were very big, which further deepened people's understanding of Dahan, Shandong.
