Story version one: Mu Ran, a good student in the 21st century, traveled back to a child in a parallel time and space like the Song Dynasty.

(From Mu Ran's perspective)
Story version two: The gentleman named Yuwen who came out actually came to a small academy in a small county town to teach writing, play the piano, admire the mountains and rivers, and live a leisurely life of leisurely clouds and wild cranes in order to avoid the entanglement of his ex-girlfriend or ex-boyfriend. Then, to no avail, he was red-lined by a little girl in his class, and ended up living happily with the dean who taught politics. (From Gu Nian's perspective)
