This is a fanfic about Tang Yuzhu from Liu Bowen's Tales: Traces of Tears on a Foggy Night. In this version, Tang Yuzhu does not acknowledge Princess Guangji as her adoptive mother in the end, but leaves on her own. Liu Bowen dies a year later, and Ding Chong returns to Princess Guangji's side to fulfill his duty as her son. Two years after that, he returns to the Central Plains to look for Little Bamboo.
This old story has been on hiatus for a long time, and I've forgotten many of the original details. I'm filling in the main plot now, but can't get to the family storyline, so please don't hold it against me.
Theme: Setting a trap and dismantling it.
I just found this article. It's very interesting. Ma'am, will you update it?
