There are three main theories why Jiangxi people are called Laobiao: One theory is that Hunan people are descendants of Jiangxi people. Hunan people believe that they are cousins ??ancestrally related to Jiangxi people, so they call them Jiangxi. He is called "Jiangxi Laobiao".
Jiangxi is the land of their parents, and Jiangxi people are their relatives. Therefore, calling Jiangxi people "old cousin" is extremely popular among Hunan people. Gradually, after hundreds of years of widespread communication among Hunan people, all Chinese people probably know that Jiangxi people are the "old cousin" of Hunan people. There is also a saying that the ancestors of Gan area believed in Feng Shui, and it was also easy to grasp the direction during migration.
I always like to carry a watch (an ancient compass), so people from other provinces call people in Jiangxi "Laobiao". It is said that most academic circles agree with the latter statement. The legend is certainly a bit bizarre.
Notes
In 368, Zhu Yuanzhang, the founding emperor of the Ming Dynasty, destroyed the Yuan Dynasty and ascended the throne in Nanjing, Jiangsu Province as the first emperor of the Ming Dynasty. At that time, all the armies under his command came to Beijing to pay homage. Zhu Yuanzhang saw that too many people had gathered in the capital, so he tried to get others to postpone their entry to the capital.
However, because the remote areas in the south were far away from the capital, they hurriedly and slowly arrived at Changsha Prefecture. Zhu Yuanzhang ordered the troops to "rest in Changsha for three days before going to Beijing." His subordinates heard wrongly. Oral instructions, misunderstood "rest" as "bloodbath" - "three days of bloodbath in Changsha". The emperor's orders come true, and those who disobey them will be executed. So the Ming army carried out a bloody massacre in Changsha Mansion.
