If you really can't get in, I suggest you:
First, you can choose the correct classified questions, so that more people will know the answers to your questions and more people will answer them.
Second, you can go to the professional website forum related to your problem, where there are many professionals who can definitely solve your problem.
Third, you can ask your online friends, they will be more sincere and enthusiastic to find the answer for you, and even go directly to the relevant websites to search.
Fourth, there are many professional forums and knowledge platforms on the Internet, and there is also a lot of information on them. I often go to forums to seek solutions to professional problems.
