How to treat many windows in a residential area in Harbin with small holes?

Harbin is very cold in winter. In winter, people will tie the curtains and close the windows to avoid the erosion of cold air and keep the room warm. Residents of a residential area in Harbin found small holes in their windows in the morning, and there were also small holes in the windows of their neighbors. How did this happen? How do netizens view this matter?

An introduction to the matter.

First, let's take a look at how this happened. You know, the window is close to home. If someone cut a small hole in the window, they would certainly hear it, but the residents didn't find it, but found it in the morning. This is really fun. Therefore, Bian Xiao thinks that the residents are definitely not at home, or this small hole is not man-made, but naturally formed. These holes may be caused by the melting of snow and the broken glass. However, Bian Xiao only speculated in this way, because the Internet didn't explain how these holes came into being.

How do netizens view this matter?

Bian Xiao also conducted a search on the Internet and found that many netizens maintained a relatively neutral attitude. They think that the residents were too careless, and there was a small hole in the window, which they didn't know or discovered afterwards. Many netizens said that the residents slept so soundly that they didn't know that someone had cut a small hole in the window. However, some people say that people who let these small animals appear are too bad, and they also smash other people's windows in winter. What happens if the window leaks? It may make the indoor temperature drop, which may make the body catch a cold.

So be careful when sleeping, and don't sleep too well. When some accidents happen again, we should get up and check, and we can't let them happen. If left unchecked, it may endanger our safety, which is also very bad.
