I don't smoke, but I found a phenomenon. When boys smoke in the toilet, they like to throw cigarette butts into the urinal, as if the urinal is their ashtray. Therefore, this design work uses the symbols of the urinal to design a bad and interesting ashtray to show uncivilized phenomena. As we all know, excretion is a very private thing, and the urinal is not convenient for several people to use at the same time, otherwise, it would be embarrassing. When I converted this symbol, I kept this setting. It can be found that I only made an incision in this ashtray to facilitate placing cigarettes on the ashtray and prevent cigarettes from falling out of the ashtray. Its main function is to emphasize a person's use scene. The reason why I emphasize a person's use scene is that smoking in public places may cause disgust if found by others, no one likes secondhand smoke. If this public place is a toilet, it will weaken this feeling and lead to this situation. It may be because the toilet is a relatively private place, and it has other smells, thus reducing people's requirements for this place. In daily life, can we still observe those strange phenomena? You have also observed some phenomena, you may as well share them with us.
