我看不到的问题。您需要说明要解决的具体问题。
请注意，您还需要将问题放在问题的正文中，而不是主题。当主题用于提出整个问题时，超过90％的时间问题需要澄清。该主题的最佳用途是使其尽可能短
，但足以帮助那些有助于决定查看它的人。

I don't see a question. You need to state a specific problem to be solved.
Note that you also need to put your question in the body of the question, not the subject. When the subject is used to ask the entire question then more than 90% of the time the question needs clarification. The best use of the subject is to make it as short as possible yet adequate enough to help those that can help to decide to look at it.
