Shanhe Vocational School: My Students Are a Bit Fierce

All the teachers: "I would rather manage thirty classes than teach one devilish class! I will definitely resign within a month of being a teacher." Director: "Teacher Ren, as long as you don't resign, everything else is easy to talk about!" Principal: "What? Teacher Ren, another student in your class has been excommunicated?" A year later, a new Shanhe Vocational and Technical College was built next to Shanhe Vocational School. Two years later, Shanhe Vocational and Technical College expanded and was promoted to Shanhe College. Three years later, Shanhe College was promoted to Shanhe University. N years later, at the Shanhe University History Museum, the tour guide introduced the founding history of Shanhe University to freshmen: "In the beginning, this was the expectation of every Shanhe person. It was the old man in the statue who single-handedly taught the devil class and became the most dazzling presence in Shanhe. Please remember his name, the most outstanding class teacher in Shanhe Vocational School, the general professor of Shanhe University, and the first honorary president of Shanhe University - Mr. Ren Fei." Also known as "Leading the Demon Class of the Vocational School at the Beginning, Leading the School to be Promoted to Shanhe University" and "The Strongest Class Teacher: Starting from Shanhe Vocational School, Promoting to Shanhe University".
