The origin of Six Doors can be traced back to the Sui and Tang Dynasties and flourished in the Ming Dynasty. With the demise of the Ming Dynasty, Six Doors became history. But from many costume dramas, we can see that Six Doors is a fearsome organization, and it is also very mysterious.

Six doors is a special existence, because there was a corresponding legal system to rule the people in society at that time. But six doors can be said to be on the edge of the legal boundary. Mainly to serve the supreme ruler directly. On the surface, it seems that our political class and criminal means are arranged in sequence from the highest to the lowest. Doing things with six doors is equivalent to the dark part behind the light.

Because the work of the imperial court is closely watched by the world, his words and deeds will be discussed, so some things are not easy to do. Moreover, in order to achieve a surprise and secretly control the overall situation, six doors were set up to serve the supreme ruler directly, and then it was convenient for him to know all aspects of information without being deceived by others. For example, we know that the court and the rivers and lakes are incompatible.

However, in court, sometimes you need to do something with the help of Jianghu. At this time, the six doors played a certain role, because it was mainly composed of ouchi experts and Wulin experts. And they have the support of the court, and everyone has a special token to walk outside. As long as the token is displayed, officials must obey him unconditionally when investigating cases. Because it only obeys the supreme ruler, and the criminal means are particularly vicious and decisive. So in the Ming Dynasty, he was revered.
