Scientific research is generally supported by a large number of experimental data, which is more convincing. And do the same experiment again, and the experimental results may appear again.

Empirical, regional, more regional, and even unrealistic. Don't you often hear speeches about experiences and practices at meetings? Look back and you will know what the experience is like. What you have experienced is feasible, and it may not be feasible for others to use the same method again.

Please forgive me if there is anything wrong.
