I welcome criticism. Please add the book to your shelf. The author is a full-time writer.

Sui Siyan, a history professor who has been single all her life and is now 64, transmigrates and becomes young again, back to the age of 18. She binds to a teaching System (a certain System that’s been forced to change its name...). Without her permission, the System even changes her gender and wants her to be the male lead’s golden finger in the early stages, becoming his teacher. Instead, she turns around and starts a private school, making both the male and female leads, as well as the villains and cannon fodder, her students.
