Solve multiple root node problem and decrease it

I write a script to find the categories which are not included by other categories. And I get this result.

Some categories should not be included by others. That is according to the discussion with other collaborators so I won't touch them. Besides, I will create some pull requests to include them in others.

Would you mind me postponing the review till April? (Thank god it is not the mega PR you mentioned in the private chat, I think I might be able to make a call for all of this by the end of today. And I still think the following suggest might be helpful, so I will just leave them) It is indeed a good idea, but I think I can only make a call when I have time to review all of this; Digesting them one by one may lead to misunderstanding and a lapse in judgment.

BTW, you did it very well in splitting the changes into several small PRs. However, you could make it better by just opening this issue, and waiting till you have had a discussion with people who is likely to review the PRs. You can start your work after you have put some effort to make sure that any overlooking has been caught in advance, and reviewers show interest in your proposal. @rootmelo92118

Oh, I am sorry to make you misunderstand. For these categories, my strategy is to include them in existing categories. If you think it should not belong to some categories, welcome to make a discussion. @IceCodeNew
