1, broken window theory's revelation is that "the first broken window" is often the starting point for things to get worse. Secondly, the deterioration of things is of course inseparable from the black hand behind it. Finally, this theory tells us that the existence of any kind of bad phenomenon is transmitting a kind of information, which will lead to the infinite expansion of bad phenomena, and at the same time, we should be highly alert to those seemingly accidental, individual and slight "faults". If we turn a blind eye to this kind of behavior, turn a blind eye, be slow to respond or fail to correct it, we will indulge more people to "break more windows", which is likely to turn into "break more windows", just like Liu Bei said, small good does not do, small evil does not do.

2, the broken window effect is a theory of criminology, the theory by James? Wilson and George? Lin Kai proposed. This theory holds that bad phenomena in the environment, if left unchecked, will induce people to imitate and even intensify. For example, in a building with several broken windows, if these windows are not repaired, there may be vandals destroying more windows. In the end, they will even break into the building. If they find that no one lives there, they may settle or set fire there.
