Garbage cans can be seen everywhere, and whether they are placed in the right place. Some garbage cans are not placed in the right place, but some places are concentrated, some places are few, or even no, like around some garages.
There are also different places where the trash cans designed are unreasonable and the distribution is not fixed. They may have been in the same place two days ago, but they will disappear two days later. There are many people in some places, so there will be more garbage. However, the opening of the trash can is too small, which is easy to throw into the ground or outside. In addition, the capacity is too small, causing the garbage cover to be full of garbage.
Therefore, there should be more trash cans in places with more people, and less places with fewer people
