I wonder what is the method they use.
One round to the back of the head.
They are marched by two guards, each one with a firm grip on the prisoner’s arm, to a tall dirt berm. The two guards, still maintaining their grip, extend their arms as to distance themselves from the prisoner. And the same time they exert pressure on the arms to get the prisoner to lean forward. A third guard then shoots the prisoner in the back of the head.
I watched a Chinese documentary on the execution of a female drug dealer. How they celebrated her last day with makeup, a good meal and friendly companions. Then several prisoners were marched as I described above for mass executions.
I doubt if this mass murderer got the celebration part.
A few decades back a Readers Digest article described a Chinese execution. The prisoner was in court, the judge read the verdict and sentence. A second after the reading of the sentence a guard shot the prisoner in the back of the head right in the court room. Now that’s swift justice!
The Mao regime used to charge the relatives for the cost of the bullet.
