But we have many Rebirth dramas at this point. Full length dramas. For example Story of Kunning Palace, Blossom, Si Jin, The Princess Royal, Lost Track of Time, and etc. Many short dramas also have Rebirth themes.
Maybe the censorship already changed their rules. After 2021/2022 there so many Chinese dramas about "Rebirth".
Yes SOKP inserted "novel writer" in the beginning + the ending to avoid censorship. But how about the other dramas?
The Princess Royal only let ML and FL said/questioned the situations to themselves like "Is this a dream? Why i am going back to my youth?". But the statement is only for ep 1. And the ending, they said, "if this is a dream, i wanna live in this dream forever." Something like that. It's a soft move and unnoticeable. Because many real ppl in this world also talked to themselves like that if something good is happening unexpectedly.
For Si Jin and Lost Track of Time, there is no opening or ending that indicate this is just a dream or story in fictional world. It just ended the story like other costume dramas.
For Blossom, also, there is no opening and ending about "dream or book story" as well. They wrapped the story with complete happy ending like other costume dramas.
