When traveling in Jakarta, Indonesia, and flying, I found a super cute phenomenon at the Sukarno Hada International Airport. The public access to the airport, whether it is the passenger passage to the boarding gate before take-off, or the arrival of the landing layer The exit passenger passage, on the white walls on both sides, will have a fire extinguisher hanging on the wall every few meters, and each fire extinguisher is surrounded by cartoons, which together constitute a pair of extremely interesting comics. It can also add a lot of fun in a hurry.
