Emperor Wu of the Han Dynasty has been in power for more than one hundred years, and the people of the former six countries have become the people of the Han Dynasty. Why are there still adherents of the Six Kingdoms? I don't think this time should be too long. In fact, it was only 60 or 70 years before Emperor Wu of the Han Dynasty, so in this respect, it was not long before the Warring States Period, that is, around 890 years. According to people at that time, this is actually only three or four generations. In other words, if there are some descendants of governors in the Six Kingdoms period, then they should still have some living habits at that time. I still keep the memory of my ancestors during the Warring States period, which cannot be eliminated in a short time. Without hundreds of years, it will certainly be difficult to eliminate after more than ten generations.
