Lin Wantang passed through a 70-year-old regimental favorite and became the niece of Lin Hongmei, the regimental favored sister-in-law.
In the original book, Dafang's family is the sister-in-law's blood donation package:
Grandpa retired and gave his only job slot to his second uncle.
His father was laid off from his temporary job and took on dangerous odd jobs to support the family, and eventually died in a machine accident.
My mother was unemployed and had taken care of the family for many years, and eventually became ill from overwork.
The older brother had no job, so his second uncle took advantage of him and charged him with stealing supplies from the factory.
Lin Wantang was forced to drop out of school and gave up all opportunities for school, work and marriage to her sister-in-law.
The sister-in-law takes the money, food, clothes and medicines from the big house to help the down-and-out male protagonist Zhou Yanchuan, and eventually marries him who regains his identity, becoming the winner in the book's life.
After Lin Wantang came through, the first thing he did was to stop the blood supply.
She brings a modern commercial complex with her, not only to change the fate of her parents and brother, but also to make the sister-in-law who obtained happiness by sucking blood in the original book see with her own eyes that the Dafang family will get better and better.
