The children asked me how Luxembourg and Iceland made "bus sweeps" have nowhere to hide. How to explain it clearly?

Bus cleaning is actually synonymous with corruption.

Luxemburg, Iceland and other countries have very small populations, only a few hundred thousand, which are very easy to manage compared with China. This can be compared with a family where parents only need to take care of one child and a teacher in a kindergarten school needs to take care of one class: it is easier to manage with fewer people.

Luxemburg Iceland is a developed country with a much longer modern development history than China. Relatively speaking, people's ideological consciousness is higher, just as parents know more than their children.

The legal systems in Luxembourg and Iceland will be more perfect. Just like if the teacher only tells the children not to copy their homework, the children may copy their homework. However, if the teacher tells the children to copy their homework, they will be called to the office to copy their textbooks. In this case, the children may copy their homework less.

There are Luxemburg, Iceland and no Tomb-Sweeping Day.
