When looking at zhangluyao's blog, he said:
I think for any problem, there are usually two solutions, one is to solve it, and the other is not to solve it (that is, to realize it can be ignored).
These two solutions are equally difficult. In fact, the latter is a bit harder, because unless there is a profound understanding of the problem, people may not realize that this option exists.
I am deeply touched. For any problem, the first step is to determine if it is indeed a problem, rather than jumping straight into how to solve it. If not solving it is a better solution, why spend time and money trying to solve it?
