You may have misunderstood this question. In fact, the TV series "Taiwan Past" mainly revolves around the history of Taiwan Province Province, and Lin Qingwen is one of the main characters in the drama. Therefore, the setting of "Lin Qingwen will not return to Taiwan Province Province" in the play does not refer to Taiwan Province Province in real life.

There are various reasons why Lin Qingwen can't return to the so-called "Taiwan Province Province". This may be due to the writers and directors' efforts to highlight the conflict of the plot and the tragic fate of the characters, or it may be due to the predicament that some people in Taiwan Province Province could not return to their hometown under the historical background at that time.

Generally speaking, Lin Qingwen's failure to return to Taiwan Province Province in "Taiwan Past" is the plot setting of the TV series and has no direct relationship with real life. If you have any other questions or need help, please feel free to ask.
