Tang Xin, the modern high school teacher, was exhausted after trying her best to save a student who committed suicide. When she opened her eyes, she transformed into Tang Wanwan, the cannon fodder concubine of the prime minister's palace. Her aunt is cruel and her scumbag father is cold. The whole government regards her as a marriage pawn and forces her to be given to the iron-blooded general Gu Chenxiao who is rumored to have suppressed his wife! On the day of her wedding, she overturned the wedding sedan, tore off the red hijab, and rode away from the wedding on a rainy night - she would not acquiesce in this life of being at the mercy of others!
Incognito and transformed into Tang Qing, she relied on her teaching skills that were engraved in her bones to fight back from a poor student with a shabby house in the mountains to a sensational academy principal in the capital. Naughty boys were inspired by her to become talents, and pedantic scholars were slapped in the face by her in public. The Prime Minister's Office hunted them down, exposed their identities, and surrounded them at all levels with intrigues in the court. While she was running a school to nurse students, she tore up the evidence of the Prime Minister's Office's crimes and dug into the old case of the general's injustice!
A woman disguised herself as a man and set up a school, breaking the rules of ethics and offering women's classes. She did not climb into the powerful and did not become a concubine. In this life, she will save herself first before saving others. She will not be anyone's wife, only Mr. Tang who controls the destiny and enlightens thousands of students.
