Translated or raw is fine. Romance or no romance fine. Nothing with more than 200 chapters. EDIT: Can be male or female MC, can be about the real or swapped child I think both are interesting.

Prince Yu Pei Haven't read this yet but the synopsis mentioned about swapping the children Dressed As A Wealthy Daughter I abandoned it halfway but yeah it belongs to this genre Fake Daughter In The 80's Currently reading this. FL is a fake daughter sent back to the countryside. The synopsis may cause confusion but it is mentioned that the OgFL is the one who wrote letters to her biological parents.
Full Marriage I feel like I have more titles to give but I'm brain ded rn and can't think of anything else
The part where I am at: The MC marries the swapped girl's fiancee who never loved her even in the swapped girl's previous life. The MC's biological younger sister Lin Xinghua loves to cause trouble for her while her biological younger brother is very fond of her. In the past life, Lin Taohua(the swapped girl and the rich family's original daughter)never had a child after so many years of marriage and after she was reborn, she told LXH that the ML had an illness. LXH causes trouble. The ML's mother is good, the second sister-in-law has a picky personality. In the chapter where I am at now, MC moves with ML to the army base.
