China has developed for thousands of years, and in this historical process, China has gradually formed the characteristics of the common development of the Han nationality with the Han nationality as the main body and a variety of ethnic minorities. Although the ethnic minorities are not as large as the Han population, they have also given birth to many different cultures, and the bó people are one of the representatives. When this nation existed, it created the mystery of the hanging coffin, which made most experts in the country puzzled. And now that this nation has almost disappeared, how did they disappear into the long river of history?

Sichuan Province was once the main living area of the [bó] people, and in Sichuan County, there is a hanging coffin scenic spot. According to historical records, the Servants were once called du palm barbarians by the Han people, with a population of more than tens of thousands of people, and once had a lot of power in the southwest area. The servants had a unique funerary culture, in which they would cut holes in the cliffs and nail wooden stakes, and then place the coffins of the deceased on it, or place one end of the coffin in the cliff cave and the other end on the stakes nailed to the cliffs. This burial method is very peculiar, and people still have not understood how the servants placed the coffin in the ancient era when there were no cranes and no cranes, and why did they do it?
If the servants still have descendants, we may be able to understand the mystery, but after more than a hundred years of existence, the servants have completely disappeared, and the reason for this is entirely because the Rulers of the Ming Dynasty were too cruel to this nation, resulting in tens of thousands of people disappearing, and at present we can no longer find a servant, and the hanging coffin culture has finally become a mystery for thousands of years.
The origin of this ethnic group is also debated in academic circles, with some experts believing that they are a branch of the Dai and others believing that they split off from the Bai. But there is no definitive evidence of which culture they belong to.
As for why they suddenly disappeared, this is because before the Ming Dynasty, the imperial court basically adopted the toast system for the ethnic minorities in the southwest, which was equivalent to giving the local people a high degree of autonomy, and the toast was the highest power holder in the local area, and the only task was to be loyal to the imperial court and pay taxes. The implementation of this system has also enabled the rapid development of the culture of the servants.
However, in the Ming Dynasty, in order to strengthen the centralization of power, the imperial court changed the toast system to the liuguan system, this area was administered by the liuguan, there was no hereditary right, but had a term of office, the promotion of this system caused dissatisfaction among the local residents, and eventually the contradiction escalated, and war broke out between the two sides.
However, under the suppression of the Ming Dynasty army, this ethnic minority completely perished on the land of China, and the mystery of the hanging coffin they left behind has become a problem that cannot be solved in the current historical circles.
