hello, I think it's better to open my own shop, because I will be more attentive.

In the future, if you encounter similar problems again, you can solve them according to the following ideas:

1. Discover the problem: you often live in the world and are always in all kinds of contradictions. When some contradictions are projected into your consciousness, the individual discovers that he is a problem and asks to try to solve it. This is the stage of finding the problem. From the stage of solving the problem, this is the first stage and the premise of solving the problem.

2. Analysis of problems: To solve the problems found, it is necessary to clarify the nature of the problems, that is, to find out which contradictions, which aspects of contradictions, and what relationship they have, so as to clarify what results the problems to be solved should achieve, what conditions they must have, the relationship between them and what conditions they already have, so as to find out the important contradictions and key contradictions.

3. Propose assumptions: On the basis of analyzing the problem, propose assumptions to solve the problem, that is, possible solutions, including what principles and specific ways and methods to adopt, but all these are often not simple and ready-made, and there are various possibilities. However, putting forward assumptions is the key stage of problem solving. Correct assumptions lead to the smooth solution of the problem, while incorrect and inappropriate assumptions make the solution of the problem detour or lead astray.

4. Check the hypothesis: the hypothesis only puts forward n possible solutions, and there is no guarantee that the problem will be solved, so the last step of problem solving is to check the hypothesis. No matter what kind of test fails to obtain the expected results, it is necessary to put forward another hypothesis and test again until the correct results are obtained, and the problem is solved.
