Japanese people like frying very much. Things because they usually eat very little. Pay attention to highlight the original flavor of food. But you can't live without oil and water. Therefore, fried meat is the first choice of Japanese cuisine, one is fried chicken pieces, and the other is fried pork chops.
Moreover, in Japanese, the pronunciation of pork chop rice is similar to victory, so preparing pork chop rice at the police station is also in the hope that the police can win every battle.
In fact, there is another saying that I don't know if it is true. Once a prisoner told all the cases after eating pork chops prepared by the police station. So since then, the police station has been preparing pork chop rice. Now it can be said to be another symbol of the police station.
