On their wedding night, Rong Qing's husband admits that he is impotent, then becomes a Buddhist disciple that very night.
Rong Qing is left in a marriage in name only. She serves her parents-in-law and uses her dowry to support her husband's family, working tirelessly without complaint.
Five years later, the Buddhist disciple returns to lay life with a woman and three children, forcing Rong Qing to agree to his taking a second wife on equal footing with her.
The Buddhist disciple sneers, “You'll never become a foremost female physician like Huairou, who is devoted to saving lives. All you know is how to count money with your vulgar, mercenary hands, then scheme against the short-sighted women trapped in the inner quarters.”
Rong Qing turns around, divorces him, establishes her own household, and builds a thriving business.
Later, her scumbag ex-husband comes looking for her and demands to know who the father of her child is.
Only to find the Regent of the realm at her beck and call, bringing her medicine for her pregnancy...
Seeing this, the plot gradually gets better. Good!
It's nice to watch, but the ending is a little rushed.
