Meta-knowledge is not a specific knowledge, but the ability to think independently. A person can judge right and wrong by his own ability and provide solutions!

Simply put, if you look at any paper, such as an algorithm, then meta-knowledge refers to the foundation needed to understand the algorithm (excluding the algorithm itself). If you are talking about the habits of tigers, then meta-knowledge means that you must first know what tigers are and what their habits mean, otherwise you will not be able to understand what the paper says.

There are three ways to improve metacognition:

1, listen to different opinions and see how others have solved this problem, or look at this matter, broaden your thinking and think about the matter itself.

2. Read more books to improve cognition. The more books on basic subjects, the better.

3, learn to disassemble the problem, the problem you encounter will be disassembled and become a small problem, the complex will be simplified, and the facts will approach step by step.

Only in this way can we improve metacognition, recognize the origin of things, and achieve the purpose of seeing mountains or mountains, and seeing the sea or the detached state of the sea.
