Lu Ze, 24 years old, a straight-through bachelor’s and master’s graduate from Peking University, thought he’d become an excellent teacher after graduation.

But…

“Lu Ze, tomorrow you’ll go to No. 3 High School’s Rocket Class as a temporary homeroom teacher. Remember, you’re going undercover. Your mission is to mislead those students.”

To carry out the mission, Lu Ze is forced to make a series of morally questionable moves:

“Our class gets a full weekend off. No morning or evening self-study.”

“Phones are allowed.”

“No dating in front of me.”

“Teachers aren’t allowed to assign any homework.”

“…”

Everything he’s doing is being livestreamed 24/7 on a reality show called Model Teachers.

The show also features rocket classes from two other high schools:

A strict 1980s-born homeroom teacher who enforces discipline with military-like precision.

A 1990s-born homeroom teacher who relies on emotional coaching and daily motivational speeches.

And then there’s Lu Ze, born in the 2000s—who lives by one motto: “Enjoy life while you can.”

At first, no one had any faith in Lu Ze’s class. But…

Two months later…

“Lu Ze, what the h*ll happened? Why did your class do so well on the midterms?”

Lu Ze: “Maybe their foundation was too good. Just wait—by finals, their scores will definitely drop!”

End of the semester…

“Lu Ze, what’s going on?”

Lu Ze: “Hang in there—next semester, their scores will fall for sure.”

One year later…

“LU ZE!!”

Lu Ze: “Don’t worry…”

Many years later…

“You were supposed to go undercover at No. 3 High School—how did you end up as principal?!”
