How to solve such a thorny problem at work?

If you encounter problems that cannot be solved within your ability, you should consult your superiors or elders in time and ask them to give tips and inspiration. They will understand your enthusiasm for work and be happy about it.

If you have a negative attitude and think that the leader is making things difficult for you and your mood is extremely low, the problem is still a problem. If you don't work hard, the problem will never solve itself.

We should overcome this difficulty and give full play to our subjective initiative and enthusiasm. Since the superior has given this task, it shows that you have this strength, and it also shows that the superior believes that you can complete it. So, ask for help, read books, look up information online, find information, work overtime and do everything possible.

When you finish, you will find that, as it turns out, there is nothing you can't pass and nothing you can't do!

The superior won't give you anything you can't do. If you really can't do it, it only shows that you are incompetent and not suitable for this position. Quit your job.
