The drama is based on the novel “Niang Zi Zai Shang, Fu Jun Bie Nao / 娘子在上，夫君别闹”, which tells the school story of a modern college girl who accidentally time-travels to an ancient school.
After entering the academy disguised as a man, Wu Wanwan is involved in a series of hilarious stories with her classmates Tang Wenqi and Qi Shan.
They work together to change the unequal distribution of educational resources in ancient times.
They are brave enough to confront the ancient notion of inequality. They set up a private school, refusing to discriminate on the basis of their class, and even admitting women to the school without charging any money, just so that everyone could study.
Even though there were many obstacles in their way, they overcome them all and eventually everyone was convinced and their approach gradually gained acceptance. They succeeded in incorporating the modern concept of education into the ancient school.
