What if I wear Japanese clothes, carry a rifle on my shoulder and have a big chicken hanging from the bayonet of the gun to take the subway 1 line?

First of all, you should make sure that there are no bricks, water pipes and other things left by buildings that can kill you. Secondly, you should make sure that no powerful public official like the police can pay your gun and eat your big chicken. Congratulations, then. I'm almost sure you can make the headlines in the evening news as you wish. Of course, it is estimated that you saw your former "glorious" image in the orthopedic department of the hospital (or the Shanghai Mental Health Center, which can be reached from Line/KLOC-0 to Line 4).
