Figure 1 shows the pending situation formed in the battle between Sun Yuexian and Fu Guangming in Beijing.
The Red Square Car Eight Ping Six General is the "General".
The black car 2 flat 4 invites the red car, which meets the conditions that can be exchanged for eating, and is treated according to "redemption".
The red square car is six flat and eight volts under the sunken bottom to do the "double car mistake" killing, which is "killing".
The black car 4 flat 2 and invited to redeem the red car, the invited party will immediately be killed by the black car 1 into 3 after eating the child. Not "redemption", but "killing".
In this case, the red side is one general and one kill, and the black side is one to one kill. The former is a prohibitive law, and the latter is a permitted law. According to the current Rule 20 ruling, the former (i.e., the red side) should be changed and the negative judgment should not be changed.

The red square car seven flat six invitation to the black car is "exchange".
The black side car 4 flat 3, can be in the next horse 6 into 5, cannon five retreat two, soldier 5 into 4, soldier six into one, the black side with one horse and one soldier in exchange for the red side a horse and a car, is "catch".
If the black car eats this son, it will immediately be killed by the red square car. Therefore, Che Liu Ping Seven is to catch and kill, from the heavy sentence of "killing".
The black square car 3 flat 4 catch the river soldier is "catch".
In this case, the red side is one against one kill, in order to allow the law; the black side is a long catch, which prohibits the law. According to the current "2020 Rules", the ruling should be changed by the black side and the judgment should not be changed.
