Cold knowledge:

Cold knowledge refers to those biased, trivial and complicated knowledge and things. This knowledge seems strange or interesting, but it has always been around our lives, but few people pay attention to it.

Cold knowledge can increase people's knowledge, broaden people's horizons, enlighten people's thinking and arouse people's strong thirst for knowledge. Like "cold jokes", cold knowledge is unpopular but useful and more attractive.

"Cold knowledge" was once called "stupid questions" because all the questions are very small and slight, and sometimes they look stupid or even "boring". However, it is these "small" problems that can stump those who think they are smart. What we can see is that in the face of these small problems, those who take solving "big things" as their own responsibility will always be at a loss and dumbfounded.
