Well, paragraphs in fiction are often broken when there's a significant change in the action, mood, or perspective. This helps make the text more organized and easier for the reader to follow. For example, if the character moves to a new place or has a new realization, that might warrant a new paragraph.
Fan Xian's identity was made public in the 60th chapter of the novel " Celebrating Years." There is no mention of the number of volumes in which Fan Xian's identity was made public, so I don't know in which volume Fan Xian's identity was made public.
Fan Xian's life experience was known to him early in the novel " Celebrating Years." The first time he suspected his identity was when he saw the letter his mother had left for him. Later, he saw his mother's portrait in the Palace and so on, further confirming that he was the Qing Emperor's son. However, the search results did not provide a clear answer as to when Fan Xian's identity would be made public. Therefore, it was impossible to determine when Fan Xian's identity was made public in the novel.
